Visitors can enjoy hiking, biking, and horseback riding on the nearby trails, including the San Rafael Swell and the Buckhorn Draw. The campsite amenities include dispersed camping, fire rings, and a vault toilet. It is important to note that there is no potable water available, so visitors must bring their own. Additionally, the area is known for its petroglyphs, which are ancient rock carvings created by various Native American cultures.
