General: Small (37-site) forest service campground in two loops near Theodore Roosevelt National Park. No hookups or cell service (despite proximity to the highway). We arrived on a Thursday afternoon in late August with no reservation and had no problem securing a site, although it filled almost to capacity by evening.
Site Quality: Many are in direct sun, but we found one that had some afternoon shade. Each site has a fire ring and picnic table. All camper pads are paved.
Bath/Shower house: There were six vault toilets (two by the entrance and two in each loop) that had sinks but no soap; they were reasonably clean. Two showers were in the other loop from where we stayed, and we did not use them.
Activities: There is access to the Buffalo Gap Trail, but we did not hike it as this was an overnight stop for us and quite hot. It is not far from the south unit of Theodore Roosevelt National Park.
It was hot when we were there (high 80s) so we just kind of collapsed upon arrival and took off the next day. The good news is you are close to the highway, but you will hear some road noise. $20 or$10 with the senior pass makes it a good deal. Cash or check if you cannot register online (no service with Verizon).
