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.
