Porcupine Flat Campground, Yosemite National Park

This interesting and primitive campground is actually far from flat, so you will probably be tucked in almost by yourself. There is no running water, and use of the creek water is discouraged unless you plan on treating it first. The road is rough, so there are only a few sites open to recreational vehicles. Altogether, there are 52 sites. There are no reservations. Sites are available on a first-come, first-served basis. No pets are allowed. The campground is open June through October.
