Muddy Mountain Environmental Education Area


The 1,260-acre Muddy Mountain Environmental Education Area (EEA) is a popular recreation area south of Casper. Access is gained by traveling approximately 9 miles south on Wyoming Highway 251 to the top of Casper Mountain, where the state road ends but continues on as County Road 505. Continue for approximately 3 miles until the pavement ends, then continue an additional 3 miles to the intersection with Circle Drive. Follow the BLM gravel road for another 4 more miles to the EEA.

Interpretive Nature Trail

The 2-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 the 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.

Natural Area

The 700-acre natural area is restricted to nonmotorized recreational activities such as primitive camping, hunting and some commercial outfitting. 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.

The remainder of the EEA consists of multi-use trails and a general recreation area. The Corral Loop Road provides motorized access to most of this area. The multi-use trail can be used by snowmobiles in the winter and ATVs in the summer. Dispersed camping is allowed in this area during hunting season.
