West of Buffalo and east of Ten Sleep in the Bighorn National Forest, the Cloud Peak Wilderness is at the glaciated core of the Bighorn Mountains and has spectacular alpine lakes and glacial carved valleys. There is a great 42 mile loop horseback riding, starting on the east side near Hunter, that allows access to the Bighorn's sheer mountain walls and crystal-clear lakes. Try the side trail over Angeline Pass to Mirror Lake.
The Hunter Corrals provides the best access to the Cloud Peak Wilderness for horseback riding.
To reach the Hunter Corrals trailhead from Buffalo, head west on US16 for 13 miles. Turn north onto FS19 for two miles to trailhead parking. This trailhead has both corrals and a camping area (very busy so make reservations).
There are other nice access points, such as the Battle Park Trailhead and the West Tensleep Trailhead. The Battle Park Trailhead is located 19 miles east of Ten Sleep on SR16 and then head north on FS27/24 to the parking area. The West Tensleep Trailhead is located off SR16 about 19 miles east of Ten Sleep and then head north on FS24 for 7 miles.
Overall, Cloud Peak Wilderness is the 2nd most popular horse trail of all 33 horseback rides in Wyoming.
