I really want to love this park. I just can't. The park offers some of the best southeast Oklahoma landscapes available but the park is dated to say the best. The updated part of the park is across the road from the lake and is more expensive to camp at and is really designed for RV's. We tent camp so have always stayed by the lake i one of the primitive sites. It took us several trips to figure out you had to pay at the visitors center by the updated part of the park. When visiting the primitive sites, by careful before you set up camp. We always have to scout the area for glass, old cans, and food scraps so the dogs don't eat anything they shouldn't or cut their paws. You also have a large influx of day use visitors during the pleasant Spring and Fall days. The plus sides are the caves, trails, and lake activities. Large boats aren't allowed on the lakes but paddle boats can be rented. We hike the loop trail around the lake and by the caves which usually takes most of the day. The bathrooms on the primitive side are in desperate need of updates so if you aren't a fan of 1940's bathrooms, beware.
