What campers say
The campground report card

Before you go
Plan your stay
Everything that decides whether Blair Valley fits your rig, your dates and your supplies, in one place.
Our take: a beautiful, free desert camp with big skies, real quiet and rock-art trails on the doorstep, about two hours from San Diego. There’s no water, trash service or hookups, the only toilet is a vault toilet, and the road turns sandy past the first half mile, so arrive self-contained, stay near the entrance unless you have 4WD, and avoid the summer heat.

Open
Blair Valley is one of eight designated primitive camps in Anza-Borrego Desert State Park, run by California State Parks. There are no marked sites: you pick a spot along the dirt roads, bring everything you need and pack everything out.
Best for
- Self-contained RVers and van campers who want free, quiet space.
- Stargazers: dark skies and wide desert views are what campers praise most.
- Hikers: the Pictograph (about 1.8 miles round trip) and Morteros (0.6 mile) trails start in the valley.
- Winter and spring trips, when the days are mild and wildflowers can bloom.
Consider this
- No water, hookups, tables or trash service; the only facility is a vault toilet.
- Past the first half mile the road is sandy and 4WD is advised; it’s washboard and muddy after rain.
- Summer heat is extreme, and campfires are banned during heat and fire-danger warnings.
- Sites aren’t level, weekends crowd near the entrance, and reviewers mention bees and military aircraft.
