Forest Service or Bureau of Land Management (BLM), offering mostly dispersed sites with no amenities—no toilets, water, picnic tables, or hookups. Some areas may have fire rings, but bring your own supplies and pack out all waste. No reservations or fees are required, though a free permit may be needed for campfires. Expect scenic settings ranging from forested mountains to high deserts. Popular spots include Eastern Sierra and Los Padres National Forest. Best visited spring through fall, these remote areas offer solitude, stargazing, and access to hiking, fishing, and off-road trails.
