Mount Diablo State Park is one of the ecological treasures of the San Francisco Bay Area. Every season in the park has its special qualities. Discover them for yourself, from the mountain’s 3,849-foot summit to its beautiful wildflowers, extensive trail system, fascinating wildlife, and distinctive rock formations.

This challenging hike cuts across the lower foothill of Mt Diablo for a scenic hidden gem of a loop up to Black Point Summit via Mitchell Canyon Rd. The Black Point Trail proper starts about one-half mile along the Mitchell Canyon Road trail, on the right just beyond the creek crossing.
