The Horseman Day Use Parking Lot (also called North Trailhead) is located off Park Road 4 on the north side of East Fork State Park and serves as the primary access point for horseback riding on the park's extensive bridle trail system.

The lot provides parking for horse trailers and access to five different horse trails ranging from 2 to 33 miles, with varying difficulty levels. Electric campsites in Loop A of the nearby campground can accommodate horses for overnight stays.
