Island Park Dam provides free dispersed camping along Island Park Reservoir, managed by the Fish and Wildlife Service with a 14-day stay limit. The large graveled parking area accommodates RVs up to 30 feet and offers level sites without road noise. Pit toilets serve the area, and campers report the location gets busy on weekends.
Anglers access the reservoir directly from camp, while the gravel surface provides stable parking for multiple vehicles. Snow can linger into April at this elevation. Cell service reaches the area, and both pets and alcohol are permitted. For additional options, campers can explore camping near Macks Inn or nearby Buffalo Campground just one mile east.
