William and Fernando gave excellent answers. The only equestrian lot is located at the east side of the park entrance.
Lost Mountain, on the east side of Route 17, has an equestrian parking area and about 7 miles of horse trails. Equestrians may also access nearly 4 miles of bridle trails on the west side of Route 17 via the Corporal Morgan Trail.
There's another lot across route 17 a little further down from the main park entrance. By the Lost Mountain trailhead.
