Reva Gap Campground — Hotel in Bison

33 months on the road and 327 campsites visited, and this is a top 10 without a doubt. Free First come first serve campground with nice campsites that seem to all have shade and sun. Some include picnic tables and fire rings. There are to be no fires at this time. There are multiple pit toilets, and the campsites are pretty private. There is a kiosk at the picnic area when you first enter that has a map showing where each campsite is. There are a few campsites not on the map and also a very large area for horses that may accommodate additional campers if all other sites are full. It looks as if they would prefer you didn't camp in the picnic area, but when I was here, there were people camping in every place possible. ( that was on a Friday night ) by Sunday 8 of the 10 - 12 possible sites were open. There is electricity on the pole in the picnic area and a box for donations if you use it. I don't think this is intended for plugging in a camper or long-term use. At the end of the camping loop there are two trails. They are both very much worth taking. I am now a huge fan of the Custer Gallatin National Forest. Where many national forest campgrounds are raising their prices, this one and many other in this National Forest remain free. Please help keep it this way by respecting the property and removing your trash...

There is a tent area / group site right off the highway, which has one electric outlet on a pole, with a donation for use. There is water and a free RV dump located in Buffalo, SD, about...

spent the night camping here, and then hiked up on top of one of the clay mountains protruding out of the gap. we sat on top and took photographs of the castles off in the distance. you can see all forms of crazy erosion taking place here. there are little flat plateaus down in the valley with clay river beds engulfing them all around. these photographs were taken at the beginning of...
