History

Bull Gap is a renowned motorized recreation area famous for a steep 35-40% grade sand hill climb. As a key part of the local Mio riding scene, it became a popular, high-traffic destination for OHV enthusiasts, particularly on holiday weekends. It is the only designated "Open Area Riding" spot in the Huron-Manistee National Forest. In the late 1990s, the area grew immensely popular, drawing thousands of spectators and riders, which necessitated increased law enforcement and specific operation plans for holiday weekends like Memorial Day. The site includes over 100 miles of trail systems (some 50-inch restricted) and the main steep hill climb, attracting both amateur and experienced riders. The area is managed by the US Forest Service (Mio Ranger Station) and requires strict adherence to regulations, including ORV stickers and designated route usage.
