Scattered across ten western U.S. States are an estimated 36,000 free-roaming wild Mustangs and burros. These animals are located in specific BLM managed roaming areas. These interactive maps from the BLM allow you to view Mustang and burro herd areas.

Visiting a Herd Area? Use Some Horse Sense!

Visiting a Wild Horse Herd Management Area (HMA) or other herd area is an exciting experience, but to minimize the effects of your presence on horses, burros, and other wildlife, please keep the following guidelines in mind:

• Watch horses and other wildlife from a distance, with binoculars.
• Travel in small groups of no more than 15 people.
• Keep the wind in your face and the sun at your back. Your scent will disperse behind you, and the animals will not see you as well with the sun in their eyes.
• Camp out of sight of water sources. This allows wild horses and wildlife free access to the water.
• Stay on existing trails, but avoid those that show frequent wild horse use.
• Leave all gates as you found them, so livestock and wild horses stay in appropriate pastures.
• Limit off-highway vehicle traffic to existing trails. Creating new trails reduces living space for horses.
• Use weed-free hay for livestock, and don't clean vehicles within the HMA. This helps to keep noxious weeds from invading.
• Report lost privately owned livestock to BLM.
• Immediately report to BLM anyone chasing, attempting to catch, or otherwise harassing wild horses or burros!
