The 24-mile self-guided Pilot Butte Wild Horse Scenic Tour can begin in either Green River or Rock Springs. Travelers should plan on approximately 1.5 hours to complete the tour, most of which is on a gravel road.
Watch for wild horses between Rock Springs and 14-Mile Hill, and all the way across the top of White Mountain. Although this is a relatively dry area with sparse vegetation, it is also home to a variety of wild animals, including pronghorn, elk, deer, rabbits, coyotes, hawks, eagles and sage-grouse, among others. Wildlife viewing is best in the early morning and late afternoon hours.
The majority of wild horses in Wyoming are located in the southwestern part of the state. The appropriate management level for wild horses in Wyoming is approximately 2,490 to 3,725 horses. Approximately 1,100 to 1,600 wild horses can be found on the public lands managed by the Rock Springs Field Office. This is a fee-free area. Sites are ADA accessible
