Mt. Rushmore and the Black Hills Travel Guide
The park has one of the largest and most beautiful territories in the state in which to ride a horse. Riding is allowed in most of the park except for some marked trails, roads, and developed areas. The mixed-grass prairie of the Badlands Wilderness Area is especially popular with riders. However, note that the weather in the Badlands Wilderness Area can be very unpredictable. Only experienced riders or people accompanied by experienced riders should venture far from more developed areas.
There are several restrictions and regulations that you must be aware of if you plan to ride your own horse. Potable water for visitors and animals is a rarity. Riders must bring enough water for themselves and their stock. Only certified weed-free hay is approved in the park. Horses are not allowed to run free within the borders of the park. It's essential that all visitors with horses contact park officials for other restrictions that may apply.
