The 1,260-acre Muddy Mountain Environmental Education Area (EEA) is a popular recreation area south of Casper. The two-mile Interpretive Nature Trail connects the Lodgepole and Rim campgrounds. It has 28 interpretive signs and is handicap accessible. Two overlooks located on the trail provide a unique view of the valley below. Travel along this trail is limited to hikers only.
Opportunities for watching wildlife are favorable as forest, sagebrush, and grasslands provide habitat for blue grouse and fox, as well as deer, antelope, and elk.
The 700-acre natural area is restricted to non-motorized recreational activities such as mountain biking, hiking, and primitive camping. The trail system inside the natural area accommodates hikers, mountain bikers, and horseback enthusiasts. A small parking area is located on the northwest corner of the boundary just east of Rim Campground. Two additional pedestrian gates are located along the western boundary.
