No water and no bathrooms, but this campground is especially popular with climbers for its backyard proximity to Happy and Sad Boulders and its dirt-cheap price. Take Hwy 395 north from Bishop and turn right onto Pleasant Valley Rd. After a half a mile, turn left onto an unmarked gravel and dirt road; the campground is not far past this intersection.
It's run by the Bureau of Land Management, and has a 14-day maximum stay unless visitors obtain a permit. Can get excessively hot in summer.
