5 Reviews of Reva Gap Campground
Nice Forest Service Campgroumd

Small campground most sites are private the vault toilets were very clean and the campground was quiet. Easy access and not far from Buffalo SD for gas and or other supplies. Very pretty scenery. We used it as a stop over on the way to the black hills and will do so for future trips

Quiet and beautiful

We stayed Wednesday and Thursday nights before the 4th of July. It's a beautiful, well kept no fee campground. A not difficult path leads you upward to a beautiful view of The Castles formation in the Slim Buttes. We will stay here again.

Solitude with a view

Great little campground nestled in the pines of the Slim Buttes. Views of more buttes and the prairie to the west with certain spots. Area is gorgeous in one of the most remote areas of SD. Can drive to campging spots a fair distance in to be away from the highway, although the traffic is almost nonexistant.

Some trails to the north of Highway 20 and on the south end of Highway 79 that can take you above and along the cliffs of the buttes with some more spectacular views. You can do some back-country camping if you camp within a certain distance of the trails (grab a forest service map at the campground for reference of trails/roads and private property).

Camping spots in the campground are clean, mowed and have a small fire pit.

Quite spot, lots of room

Really liked this free spot a few miles east of the main hwy. Great if you are traveling to the Badlands from the north. Lots of spacious sites here with established fire pits and several toilets. Coyotes serenaded us throughout the night!
