Things To Do


This campground is at the foot of the Shirley Mountains, a remote range in a large basin between the Medicine Bow and the Ferris Mountains. The Shirley Mountains offer fantastic hunting opportunities and fishing in Sage Creek. Aspen, limber pine, lodgepole pine, big sagebrush, shrubs, grasses and forbs make up the nearby vegetation. Pronghorn, mule deer, elk, coyotes, grouse, and golden eagles will wow the wildlife watching enthusiasts.
