We stayed at little bluestem campground in the Hell Creek area, where we camped in a tent. The lake was beautiful and the weather was nice. we went on a short hike on the dakota trail, which was very well kept. we do not own a boat or mountain bikes so there was not a ton of stuff for us to do. the mountain biking looked really fun. and I bet having a boat would have made it even more fun. The only reason I am not giving it 5 stars is because it was mainly for RV's. which me and my other half are not all about. There are about 20 different campsites and Little Bluestem is the ONLY primitive one. we arrived and there were two RV's in the two best spots at the PRIMITIVE campground.
