Boulder Basin Campground
Black Mountain Road is in poor condition at this time. 4-wheel-drive is recommended.
The campground has a "Q" configuration with camp sites on top of the letter having a delightful vista while sites on either side have tower boulders for a backdrop. Magnificent Ponderosa and Sugar pines and other conifers are found throughout the campground. This is a campground for hikers, mountain bikers, bouldering enthusiasts, and anyone looking for quiet and solitude - well worth the challenge of the road to the campground.
The Black Mountain Lookout Tower is accessed via hiking a dirt road from campground and offers breathtaking views of the area.
Holders of Golden Age, Golden Access, America the Beautiful Senior or Access Passports are entitled to 50% campsite fee reduction. Holder of the passport must be present.
