Black Rock Campground Access provides 11 campsites along the North Fork Boise River, 20 miles north of Idaho City at 4,300 feet elevation, with vault toilets and hand-pumped drinking water.

The campground offers direct river access for swimming and paddling, with sites 1, 2, 7, 8, 9, and 11 providing creek-side locations. Access via Forest Road 327 is a rough dirt road graded only a couple times yearly, so plan accordingly for vehicle conditions.
