Holding most of the Eldorado Mountains bordering the Colorado River and Lake Mohave, Unit 266 offers hunting for desert bighorn sheep and a few mule deer. Hunters can use roads to access sheep hunting areas, or they enjoy the unusual opportunity of using a boat on Lake Mohave.

Hunters report seeing a few different rams, making for enjoyable hunting. Most rams are in the Boy Scout Canyon and Burro Wash areas. Spot-and-stalk hunting is physically demanding. Resident deer numbers are low.

Mostly desert terrain with rugged, steep mountains and rocky ledges, particularly in Black Canyon and Eldorado wilderness areas. Almost all hunting is inside Lake Mead Recreation Area. A small part is managed by the Bureau of Land Management. Softly rolling desert hills are at the base of the mountain ranges. Broken granite can make for unstable footing during hiking.

Cactus and creosote brush and white bursage at lower elevations with mahogany woodlands at higher elevations.

Roads lead to good starting points to hunt almost all areas. In the Lake Mead National Recreation Area, which is open to hunting, access is good on a network of NPS roads. Boats may be used to reach starting points to hunt along Lake Mohave.

Boulder City is in the unit and offers lodging. Some hunters might choose to travel farther to Henderson or Las Vegas, which is about 30 minutes away.
