Sylvan Lake Campground is a 39-site campground at 6,200 feet elevation in Custer State Park with direct access to Sylvan Lake for swimming, canoeing, kayaking, and fishing.

The campground offers both tent sites and RV sites (limited to 27 feet) with electric hookups, flush toilets, showers, and potable water, plus a nearby lodge with boat rentals and supplies.

Note: Large RVs should approach via SD Highway 89 from Custer rather than the scenic Needles Highway due to low, narrow tunnels; sites are close together and best suited for smaller camping units.
