Black Rock Reservoir is accessed via a challenging 17-mile paved road (Black Rock Road) featuring narrow single-lane sections with 1,000-foot cliff drops, no guardrails, and wooden bridges—not recommended for RVs or those afraid of heights.

The small PG&E-operated campground at 4,000 feet elevation offers 10 sites with vault toilets and water during open season, with a boat launch available year-round (weather permitting).

The road is typically open all year but can close due to snow; best visited late winter through early spring for scenic wildflower blooms and waterfalls.
