South Fork Group Campground is the largest group camping facility in the Crystal Basin Recreation Area at 5,200 feet elevation, accommodating up to 125 people or multiple single-family sites with a group cooking area and individual campfire rings.

The South Fork of the Rubicon River is within walking distance, offering excellent fishing and swimming access, while nearby Gerle Creek Reservoir (5 miles north) provides non-motorized boating opportunities.

This primitive campground has vault toilets but no drinking water on-site; visitors must bring water or treat stream water, and gates remain locked with combinations provided after reservation.
