The Glenwood Dunes Trail is the only equestrian trail at the National Park. Horseback riding is prohibited on all roads. There is no horse rental concession. The trail is open to horses from March 16 through December 14 unless there is sufficient snow cover for cross-country skiing. In the parking lot and picnic area, all horse excrement must be bagged, removed from the area, and disposed of appropriately. The parking lot is large enough for horse trailers.
