Click Residual: A Query Success Metric

How do you find out which queries need the most improvement? Look at the ones that are underperforming compared to their expected number of clicks. If you look for low click-through rate (CTR), you’ll find underperforming queries, but they’ll almost all be in the long tail. Improving those won’t make an overall improvement. Click residual is a metric that combines CTR with overall traffic to give a useful number.

To find the queries with the most impact, start with the click count. “Click residual” is the difference between the expected number of clicks and the actual number of clicks. When that is negative, you can see how many times a customer did a search, but wasn’t satisfied enough with the results to click, relative to the overall performance of the search system.

$11 Base for Magnetic Keys and Paddles

Want a base for your spiffy new Morse Code paddles with a magnetic mount? Try this jeweler’s bench block. It is 13 oz. (375 g), has a shiny surface that magnets stick to, and a grippy silicone base. Plus, it is only $10.99.

Keyer base

The key is a UMPP-Academy made by GM0EUL. It looks like other 3D-printed keys, but it uses the same precision bearings that Begali uses. I have the extra magnets mounted on the sides of mine to increase the force needed to make contact. With the built-in magnets, it was just too touchy for my big, clumsy fingers.

It is plugged into an Ultra PicoKeyer, which is more keyer than I’ll ever need.

The Power of Suggestion

This article was in the January-February 2020 edition of BSA Advancement News. That issue is not available in the BSA’s online archive so I’m republishing it here. Emphasis is in the original.

The Power of Suggestion

We’ve all heard of the ‘power of suggestion’ and how it can influence our lives and the lives of those around us. If someone or something suggests to you a specific outcome, your expectations can play an important role in achieving that out-come. The reason for this is that the way we anticipate our response to a situation influences how we will actually respond.

In Scouting the ‘power of suggestion’ frequently manifests itself by leaders attempting to influence a Scout’s behavior, actions, advancement etc. by making a ‘suggestion.’ Typical examples include telling Scouts that it is ‘suggested’ they: (1) wear the full field uniform to a Scoutmaster conference; (2) type the Eagle Scout Rank Application; or (3) type the Scout’s statement of ambition and life purpose a certain length. For Eagle Scout service projects, some leaders have ‘suggested’ Scouts should work toward a certain typical standard stating for example that 100 hours is typical of what is needed to show sufficient leadership to successfully complete an Eagle Scout service project. However, Scouts will frequently interpret a ‘suggestion’ as an indirect instruction that they must comply with rather than just an alternative they might consider.

Guide to Advancement, Section states “Councils, districts, and units shall not establish requirements for the number of people led, or their makeup, or for time worked on a project.”

Leaders may defend these practices by saying that they were merely ‘making a suggestion’ and not establishing a minimum standard. But what was their real intent? Obviously, it was an attempt to influence the Scout’s behavior and actions in a specific way. In reality the above examples are nothing more than an attempt to set additional minimum standards beyond those necessary for rank advancement. This is just an indirect way of adding to requirements, which is not allowed.

From the Scouts’ perspective, the problem with such “suggestions,” however well-meaning, is that Scouts will frequently interpret a suggestion from an adult as an indirect instruction that they must comply with rather than just an alternative they might consider.

To better understand this let’s look at the context of how a ‘suggestion’ is given. When someone in a position of authority, such as a parent, unit leader, employer, or other professional makes a ‘suggestion’ more than likely they are expressing their expectation of a certain outcome. For example,

  1. If a doctor suggests that a patient stop a certain behavior, is the doctor really making a ‘suggestion,’ or are they telling the patient the outcome the doctor expects?
  2. If a teacher suggests that students study certain topics overnight, is that a ‘suggestion’ or a warning about a potential pop quiz the next day?
  3. If an employer suggests that you do something, is that really a ‘suggestion’ or an indirect way of telling you do something? If an employer suggests that an employee might want to get a report done before going home today instead of waiting until tomorrow what would the expectation of that employee?
  4. If a parent suggests that one of their children clean up their room, make their bed, take out the garbage, etc., are they really making a ‘suggestion’ that the child doesn’t need to follow?
  5. If the Scoutmaster ‘suggests’ that that a Scout do a certain something is that a ‘suggestion’ or is the Scoutmaster communicating an expected performance standard?

The examples above should make it clear that when someone in a position of authority makes a ‘suggestion’ that in reality they are communicating a performance expectation. Likewise, in Scouting, when adult leaders make ‘suggestions’ to Scouts, they will undoubtedly interpret those ‘suggestions’ as instructions that they must comply with. Don’t fall in the trap of creating additional requirements and expectations that are not permitted or allowed by calling them “suggestions.” Praising positive actions is a much better approach and ultimately one that should be much more successful in achieving the desired outcome.

I have uploaded this full issue here: The article is on pages 6 and 7. The issue should be in the Advancement News archive, but it is not in the list and even creating the expected URL by hand doesn’t find a PDF. They changed the filename format between the previous and next issue; I’ve tried both formats. If they ever upload it and fix the archive, I’ll link to it. My copy is from my email subscription to the newsletter.

RF Exposure Calculations for Emergency Commmunication

I’ve calculated some safe distances for RF exposure in typical emergency communication situations. These are for a 5 W HT (handheld radio) or a 50 W mobile, on 2 m and 70 cm, each with typical antennas. The results may also be useful for other VHF/UHF portable activities, like ARRL Field Day, Summits on the Air, or Jamboree on the Air.

Very short version: The 6-7 foot social distance we’ve learned to keep is safe for a typical fixed or mobile em-comm deployment. This is the distance between any part of the antenna, including the radials, and a member of the general population. 5 W HTs are safe for handheld use.

The FCC introduced new RF exposure rules for amateur radio in 2021. Hams used to have special exemptions, now we need to do RF exposure evaluations for all uses. If your transmitter and antenna are like the setup used for these calculations, you might be able to use these results. If yours are significantly different, this should help you get started.

Rf safety sign

The Details

There are different rules for controlled environment (the operator and other people aware of the transmitter) and uncontrolled environment (everyone else). There are also different evaluation methods for handheld transceivers (HTs) and for transmitters (antennas, really) far enough away to give a more even exposure to the whole body.

Handheld Radios

Rf exposure sar

For transmitters very close to a person, the FCC uses specific absorption rate (SAR) evaluations, which are time-consuming and expensive. Those measure localized heating in small areas of the body, either a 1 g or 10 g mass.

This article from the ARRL QEX magazine looks at existing SAR evaluations for commercial radios that use frequencies close to amateur bands.

Amateur Portable Radios (Handheld Transceivers): Exposure Considerations Based on SAR.

The test setup has the HT held 2.5 inches away from your mouth. Based on those measurements, a 5 W HT on 2 m is quite safe. It would need to put out 20+ W to reach the SAR exposure limit. A 5 W 70 cm HT is safe, but probably just under the SAR exposure limit.

Higher-powered HTs, like the 8 W models, are probably over the safe exposure limit on the 70 cm band.

Larger, high-gain antennas might actually be safer. In the ARRL calculator, those would have higher gain and require more distance. In a SAR evaluation, the larger antenna spreads the radiation over a larger area, so it does less localized heating.

This article also uses the occupational exposure limits, similar to the controlled environment limits. And the measurements use a 50% duty cycle, for example, transmitting for one minute, then receiving for one minute. This is a far higher duty cycle than any field operator would have.

The Conclusions section of the QEX article starts with this statement, “A careful but limited examination of SAR test results available in the FCC’s equipment authorization database suggests that handhelds commonly used in the amateur radio service would not exceed exposure regulations based on the magnitude of local SARs.”

Mobile and Temporary Fixed Stations

Rf exposure hf 2

Short version (controlled / uncontrolled), using the worst case across the two bands for each situation.

50 W mobile (field operator): 2.1 feet / 3.6 feet
50 W mobile (net control): 4.7 feet / 6.6 feet

People inside a car with a rooftop antenna are shielded by the car’s metal roof. Exposure is also reduced because the antenna radiates out, not down. The highest emission is straight out, perpendicular to the antenna element. There is little or no emission up or down in line with the antenna. If you can see the antenna through a window, like a trunk-mounted antenna, keep the suggested safe distance.

I used the ARRL RF exposure calculator. I’m including results for a 5 W HT, though the SAR evaluation probably should be used instead.

I used these inputs to the calculation:

Mode duty cycle: 100% (FM).

Transmit duty cycle: for a field operator, one minute out of ten, for net control, five minutes out of ten. Reducing the field operator duty cycle more does not change the results.

HT antenna gain: 2.15 dBi, probably optimistic. This assumes that the antenna and your hand (the other element) act like a 1/2-wave dipole.

Mobile antenna gain: 3.0 dBi (2 m), 5.5 dBi (70 cm). These are the specs for the Comet SBB-5. That antenna is: a) Comet’s most popular mobile antenna, b) the right size to not get caught on trees when roof-mounted, and c) the mobile antenna I own. Other antennas the same length (38 inches) will probably have similar gain, because physics.

Operating frequencies: 146 and 446 MHz.

Include ground reflections? Yes.

Detailed results:

Radio Usage Band (MHz) Environment Distance (feet)
5 W HT field operator 146 controlled 0.55
5 W HT field operator 146 uncontrolled 0.95
5 W HT field operator 446 controlled 0.45
5 W HT field operator 446 uncontrolled 0.78
50 W mobile field operator 146 controlled 1.9
50 W mobile field operator 146 uncontrolled 3.3
50 W mobile field operator 446 controlled 2.1
50 W mobile field operator 446 uncontrolled 3.6
50 W mobile net control 146 controlled 4.3
50 W mobile net control 146 uncontrolled 6.0
50 W mobile net control 446 controlled 4.7
50 W mobile net control 446 uncontrolled 6.6

For more information and a deeper understanding of the issues, dig into the ARRL resources on RF exposure.

If you want safety signs for your deployment, blue “notice” signs posted at the uncontrolled environment limit are a good choice. These might also keep spontaneous volunteers at a respectful distance. Click on this image to go to Flickr, where you can download a full-sized JPG for printing.

Scout Backpacking Around the SF Bay Area

I’ve written a series of articles about backpacking trips that work for Scouts ages 10 to 14. Some have a “split hike” possibility where older, stronger Scouts can take a different route to the same campsite.

See you on the trail!

Backpacking: Pioneer Outpost at Cutter Scout Reservation

The Hike

Not especially well-marked if you want to make it a loop, but easy to follow on a fire road if you make it an out-and-back. This campsite is a couple of miles from the main part of Cutter, past the COPE course, down into a small valley. When you hit a decent-sized meadow on the downhill side of the road, you’re there.

If you know a Scouter who’s taken the High Adventure Training (HAT) course at Cutter, they have probably hiked the whole loop. GPS tracks are available, if you ask nicely.

Why Go Here?

Who knew there was a backcountry campsite at Cutter? It won’t be booked up by tourists from the midwest, that’s for sure. Give it a try.

There are a couple of small campsite just off of Butano Fire Road, McKie and the ESAR Outpost. I’d choose McKie, which is on top of a ridge and has nice views, but it only has room for a few tents. The Pioneer outpost is a meadow big enough for a few patrols.

Reservations and Planning

The backcountry campsites are $6 per person per night.

The water source is South Fork Butano Creek, a bit up the road towards the main camp area from the campsite. You’ll be carrying water back to the campsite and purifying it.

Cutter Scout Reservation was damaged in the 2020 CZU Complex wildfires. It may be a while before the camp is rebuilt and can reopen.

Backpacking: Castle Rock State Park

Backpacking castle rock

The Hike

This is a loop, with the trail camp 2.5 miles from the parking lot. One side of the loop is a dramatic trail along the side of the ridge. with views out to the ocean on good days. Our Scouts call it the Cliff Trail, but its official name is the Saratoga Gap Trail. The other half of the loop goes through a woods along the top of the ridge, the Ridge Trail. The elevation gain/loss for the full loop is about 1200 feet.

Why Go Here?

The hike is lovely. You’ll see lots of day hikers. With 25 camp sites, it rarely fills up. This is also one of the few trail camps where a campfire is allowed, only in rainy season, of course.

You will hear a few loud motorcycles on Skyline Boulevard, and the nearby gun range is active until 4 or 5 PM. Also, watch out for poison oak, it is very common near the trail camp.

Reservations and Planning

Parking is $10 and you need exact change. Bring it, because the ranger kiosk is usually not staffed. The parking lot fills up, so plan to start your hike early.

Campsites are $15 per night with an $8 processing fee. For two sites and a group of 13 or more, there is a flat fee of $25.

Reservations can be made 60 days in advance, online.

15 of the 20 campsites are available by reservation only as part of the Santa Cruz Mountains Backcountry Trail Camp System. Five campsites are available first come, first served. This is a change from before, when all sites were first come, first served. See the reservations page below for details.

Backpacking: Manzanita Ridge at Henry Coe State Park

Backpacking manzanita ridge

The Hike

Three miles, with elevation gain loss of +/- 500 to 600 feet depending on which group camp you stay at and which route you take.

The first part of the hike has three options. The ranch road follows the crest of the ridge, so it has more views and a bit more climbing. The Springs Trail is on the sunny south side of the ridge, going mostly through meadow. The Forest Trail is on the shady north side of the ridge. The Forest Trail also has a nature booklet and is great for doing some tree and plant identification.

I like to go out on the ridge-top ranch road and return on the Forest Trail.
There are ten group camp sites stretched out along about a half mile of trail. Personally, I like site 10, at the end. It has a big meadow to run around in and some trees for protected camping spaces. it also has a nice view to the west. Site 5 is on top of a knoll and is also a a nice spot. Several of them are nice, really.

Why Go Here?

In all the times I’ve camped here, there has never been anyone in another group camp site. Maybe a group at the horse camp, but I think that was only during the day. The sites have plenty of room, picnic tables, and quiet nights.

The hike along Manzanita Ridge is a guaranteed opportunity for Scouts to do the nature requirements for Second Class and First Class (ten animals and ten plants). I always see a dozen or more wild animals on this loop—wild turkeys, quail (usually by sound), hawks, vultures, owl pellets, meadow dug up by wild pigs, pocket gophers—it’s a long list. Don’t miss the Acorn Woodpecker granary tree where the three trails meet at the south end of the ridge.

The Forest Trail is a nature trail with numbered markers, starting at the south end, but the brochures aren’t always stocked at the start of that trail, so see if the visitor center has a copy.

A split hike option is possible here, with a challenging hike over to Middle Ridge, then down to Poverty Flat and back up to the group camps. This is a great workout for a Philmont shakedown.

Stop by the visitor center at headquarters and ask about water conditions and weather. The water varies from none to not enough, but it is conversation. While you are there, you can buy their nice guides to the plants and animals of the park. You can even buy a patch. We know it is real Scouting when there is a patch.

Reservations and Planning

The Manzanita Point group camps do not have water. Each group can bring one vehicle in to carry water and other things. That vehicle will stay in the campsite. The road is pretty rutted and steep in places. I’ve driven it in a minivan, but some people would not be comfortable doing that.

The have been putting in new vault toilets and some water tanks, so that situation might have improved. Call and ask for details.

The group sites are $75 per night, plus an $8 service fee. Two vehicles are allowed only for transferring equipment to and from the camp site. They cannot park there overnight. If the road is wet, four wheel drive might be a good idea, though I’ve driven it wet in a minivan.

Reservations can be made six months in advance.

Coe is hot and dry in the summer. Winter and spring are the best times to go.

Large areas of Henry Coe State Park were burned in the 2020 SCU Lightning Complex fire, but this portion of the park was not affected.

Backpacking: Black Mountain Trail Camp at Monte Bello Open Space

Backpacking black mountain

The Hike

About two miles with 600 feet of up and down, just enough up and down to feel like a real hike. The trail goes through open grasslands with nice views along the headwaters of Stevens Creek.

There are a couple of options, taking the trail or the road. They are about the same distance and elevation gain/loss, so let the Scouts choose the route.

Why Go Here?

Lovely hike and a nice, roomy group camp area, what’s not to like? If the fog doesn’t roll in, you’ll see some stars. You can also get a nice view of the Santa Clara Valley. Hike up near the actual summit of Black Mountain (past the radio installation), then take the use trail east, towards the valley. At the edge of the meadow you can stand on some rocks and get a peek at the valley all lit up below. Camping is the only way to get that view, because the park closes at sunset.

There is a split hike option for older, stronger Scouts to take a more difficult route to the same camp site. Drop off the crew at Hidden Villa in Los Altos HIlls. They’ll walk through the farm, then start on the Creek Trail and hike up into Monte Bello Open Space Preserve. This is a 9 mile hike with 2400 feet of climbing, so much more of a challenge.

You can add a second challenging day by continuing from the trail camp up to Skyline Boulevard. Take the Indian Creek Trail down into Stevens Creek Canyon, then the Canyon Trail downstream, then the Grizzly Flat Trail up to Skyline. Arrange to have your ride meet you there. That hike is another 2500 feet of climbing. The two days together are a “half traverse” of the Santa Cruz Mountains. Hike the Skyline to the Sea Trail to complete the traverse.
Backpacking black mountain night

Reservations and Planning

Reserve the group camp with a web request on the Midpeninsula Regional Open Space District site. You will need the vehicle descriptions and license plates to register, so plan your rides early. The fee is $2 per camper per night.

For the split hike option, Hidden Villa is closed to the public in July and August. It is probably too hot to do that hike in full summer anyway.

If a storm comes through, the wind seems to be funneled through the group camp meadow. Make sure your tent is staked down.

Backpacking: Eagle Spring Camp at Mission Peak

Backpacking eagle spring

The Hike

I recommend starting at Sunol Regional Wilderness Preserve and hiking to Mission Peak from the east side. That trail is longer, 5.5 miles, but not as steep. Also, the overnight parking is much safer because the park is closed overnight.

The hike is nearly all on fire roads. That is a harder surface, but our Scouts like it because they can walk side by side and talk the whole way.

About halfway up, there is hairpin turn with a driveway to a house on the north side of the trail. The interior of that turn has a bunch of old building foundations. This is a convenient spot to stop and have lunch or a serious snack.

It will be clear when you get close to camp, because Mission Peak will be right in front of you. When you hit the tee-junction, turn right, and you’ll be at the camp right away.

The trail rises 2000 feet from Sunol to the top of Mission Peak, but Eagle Spring Camp is about 400 feet below the peak, so you only have to carry your backpack up about 1600 feet of elevation.

Why Go Here?

The campsite has awesome views of the valley across to Mt. Diablo. You can watch the traffic jam on I-680 while you sit and relax. I had that view as my screen background for quite a while.

Mission Peak officially closes at sunset, even though you are likely to see dozens of people on the summit at that time. But they have to walk all the way back down in the dark and you only have to walk back to camp.

To get to the peak, take the trail up the south side. The north side approach is the worst trail in the Bay Area, steep and rutted. The south side is a perfectly normal trail.
Backpacking eagle spring night 1

Reservations and Planning

Normally, I’d say the East Bay hills are too hot in the summer, but I’ve camped here in early July and late September and it was fine. Not sure I’d choose August as a first choice, though.

$5 per night per person plus $8 booking fee. Open all year. To make a reservation, call 1-888-EBPARKS or (888) 327-2757 , press option 2.

The trail from Sunol crosses the Olohne Regional Wilderness, so each hiker 12 years or older will need a wilderness permit. Those are $2 each and can be purchased in-person at Sunol or over the phone. Fee for in-person purchase is $2/person/year; by mail/phone/online $4/person/year for first five permits and $3/person/year for each additional permit after five. You need a paper copy of the permit, so buy them seven days in advance if you aren’t getting them in person.

Backpacking: Boulder Creek Scout Reservation

Backpacking BCSR

The Hike

Loop trail, 3.5 miles total, about 600 feet of uphill to the campsite and returning.
Camp in a spacious redwood grove. I prefer the Upper Redwood campsite to Lower Redwood or Meadow. Meadows are lumpy and cold. Upper Redwood is just a little nicer.

Why Go Here?

It is a nearby, easy trail, and easy to get reservations. It is a year-round trail, though it could be cold and rainy in the winter.
The redwood grove is a lovely spot with tons of room for patrols to spread out. There are other campsites at the lower end of the redwood grove and in the meadow, but I like the Upper Redwood Camp best. Meadows look nice, but they are lumpy to sleep on.

Reservations and Planning

Reserve the site through Pacific Skyline Council. It is best to avoid camporee weekends when the parking will be over 100% full.
It can be wet and cold there in the winter and you can get plenty of fog drip from the redwoods in the summer, but that is part of being there.

Backpacking: Berry Creek Falls in Big Basin

Backpacking big basin 2

The Hike

From Big Basin State Park Headquarters, hike the Skyline to the Sea Trail to Berry Creek Falls, then hike up the Berry Creek Falls Trail past Silver Falls and the Golden Cascade, then continue on to Sunset trail camp. The closest water is at Berry Creek, so fill up there before hiking to the camp.

This can be turned in to a two-night trip if you start by camping at the Jay Trail Camp in the Big Basin headquarters area.

An alternate route is start at the Rancho del Oso Nature Center near Waddell Beach and walk upstream to Berry Creek Falls and Sunset Trail Camp. This an out-and-back hike, roughly 7 miles each way, with an easy downhill back to the trailhead. You can even run into the Pacific Ocean at the end! But you’ll miss the old growth redwoods, which are all in the narrower upstream canyon that couldn’t be logged.

Why Go Here?

The Berry Creek Falls Loop is the most popular trail in the park, and probably the most popular long trail in the SF Bay Area. You’ll find plenty of reasons to hike it. But backpacking means you can be on the trail when fewer people are there. Maybe you want to hike the loop so that you go to the falls on the morning of the second day, so you’ll be there in the morning before the crowds arrive.

Campsites are $15 per night with an $8 processing fee. For two sites and a group of 13 or more, there is a flat fee of $25.

Big Basin State Park was heavily damaged in the 2020 CZU Complex wildfires. It may be a while before the camp is rebuilt and can reopen.

Backpacking: Black Diamond Mines

The Hike

About three miles from the parking lot with 300 feet of climbing and 150 feet of descent, reversed on the return trip. The destination is the Stewartville Backpack Camp.

Why Go Here?

I haven’t visited this one, but it looks like a nice campsite with a fairly easy hike, plus some interesting historical sites, including a mine tour.

The camp site is a single group site, so you’ll be on your own. Redwood HIkes says:

Stewartville is a single-site trail camp at the edge of a huge, sweeping cow pasture. The vast swath of open, gently sloping grassland, which is a strikingly deep green in spring, is often dotted with cows. It kind of feels like you’re a cowpoke camping on the range.

Reservations and Planning

$5 per night per person plus $8 booking fee. Open all year.

Backpacking: Angel Island State Park

Backpacking angel island 3 adj

The Hike

First, you take the ferry from Tiburon, so there is some driving and coordinating with the ferry schedule. Once you are on the island, your campsite is a mile or so away mostly on paved roads. Hiking all the way around the island is five miles, so you can’t go too far.

You’ll want to hike to the the top of the Island, Mount Livermore, but do that when it isn’t shrouded in fog. I’ve been to the top in the fog and it is amusing, but the views aren’t that great.

Why Go Here?

There is nothing quite like camping on an island. Camping on an island in the middle of San Francisco Bay with a clear view of Oakland, San Francisco, and the Golden Gate is even better. Also check out the light show on the Bay Bridge. It is on the side of the bridge facing Angel Island.

Make some time to visit the immigration station and other historical sites. The Immigration Station is a National Historic Landmark and a great choice of a place to visit for requirement 2a of Citizenship in the Nation merit badge.

Reservations and Planning

Angel Island can be very cold and windy. The best time of year is October, maybe extending into late September and early November. October is the brief break between the cold summer ocean upwelling that brings the fog and the winter storms that bring rain.

Your camp site will either be the West Garrison or North Garrison group sites on the windward side, or the Secret Service Camp in a well-sheltered site on the leeward side. The group camps have better views and the service camp is warmer.

Reserve the service camp (it’s not on the map) by calling the Service Camp Coordinator at the Angel Island Conservancy (Programs « Angel Island Conservancy). Talk to them to arrange a service project and you’ll have the use of the service camp. Don’t try to find it on the map, it isn’t there. I’ve seen the sign for it, but I’m not telling.

Camp sites open up for reservations six months in advance. Be a sniper and reserve them on the morning of the first day they are open.
Do not miss the last ferry! Chartering a boat at the last minute is quite expensive.

Backpacking: Coast Camp at Point Reyes

Backpacking coast camp 1

The Hike

Two mile easy hike through tall brush. The highest point of the trail is halfway there, about 300 feet higher than the start or end. The last time I was there, I realized I left something in the car, so I just hiked back and got it. That was a year after my knee surgery and I wasn’t in great shape, so yeah, easy hike.

You want to park at the Laguna Trailhead, but that parking lot fills up often. Don’t be surprised if you end up parking a quarter mile away along the road. It is still an easy hike.

You can also start at the Limantour Trailhead, but check the tide tables for your hike in and hike out times, because the beach portion of the trail can be soggy or underwater.

Why Go Here?

The beach! If you make it a two-night campout, there is great day-hiking up and down the coast, plus a challenging hike to the summit of Mount Wittenberg. That summit is part of the Rim of the Bay patch series.

A campfire on the beach is a great way to end the day, but dress warmly because the wind off the Pacific Ocean can be really cold any time of year.

Backpacking coast camp 2

Reservations and Planning

Getting a reservation is the hard part. Plan on being a sniper and making a reservation six months to the day before your planned outing. Log on and make that reservation before your morning coffee is finished brewing. Start checking a few days before to make sure you understand the system and the earliest date.

Based on two visits, campsites 8 and 9 were very windy, and sites 13 and 14 were a bit more sheltered. I would expect sites 1-7 to be less windy. We had Scouts looking for rocks to keep the lid from blowing off of the pot. Of course, they were set up on top of the raccoon box at a convenient height. I set up my stove on the ground in the lee of the raccoon box.

A permit is required for beach fires, get one at the visitor center—Beach Fires Within Point Reyes National Seashore – Point Reyes National Seashore (U.S. National Park Service).

The hardest part of the trip may be driving to Point Reyes on a Friday or Saturday. On Friday, you may need to leave after lunch to avoid the traffic across the Golden Gate Bridge. Plan on having all the cars stop at the visitor center to regroup. You’ll need to pick up your camping, parking, and fire permits there anyway.
