Black Rock Walk-in Tent Campground offers 10 first-come, first-served walk-in tent sites on the western shore of Little Grass Valley Reservoir at 5,000 feet elevation, with a nearby boat launch providing direct access for fishing and water sports.

The campground features vault toilets, potable water, picnic tables, and fire rings at each site, plus an accessible fishing trail and the scenic 13-mile Lakeshore Trail for hiking and mountain biking.

The campground operates seasonally (typically late spring through early fall) with a $23 nightly fee and enforces a 14-day stay limit; note that water may not be available during early and late season when the system is winterized.
