Backpackers' campgrounds are available for wilderness permit holders to spend one night before and one night after a wilderness trip. 

Camping is limited to one night at a time. Reservations are neither necessary nor required. However, a valid wilderness permit is required to stay 

at the campground. The fee is $6 per person (pay using envelopes at the campground). Parking is not available directly at campgrounds; 

instead park at designated overnight parking areas and walk to the backpackers' campground.

Yosemite Valley: The backpackers' campground is behind North Pines Campground (and across the footbridge).

Open April through mid October (approximately). 

If arriving at night, please be quiet as you unload your car in the unloading zone and walk to the campground. 

This campground has vault toilets and no potable water (potable water is available nearby in North Pines Campground).
