Bull Gap

Bull Gap Hill Climb is the ONLY designated motorized ‘Open Area Riding’ on the Huron-Manistee National Forest. The sand hill is 0.2 mile and at a 35 – 40% grade.

Bull Gap is open to all vehicles with a valid DNR ORV trail sticker. If you chose to use hill climb in a vehicle 50” wide or less, you are required to use the 50” return trail to return to the bottom of the hill. Users in motor vehicles greater than 50” are required to use the full-size motorized vehicle return route.

“ORV Trail, very wide (technically meets Route specification but restricted to ATVs/Motorcycles). Sandy and whooped to the north, rocky and hardpacked to the south. Varies from flat/open to hilly/open. Several loop options. Includes hill climb/scramble area “Bull Gap Hill”. Trail recently (2011) widened and no longer any 50″ sections, all at least 72″ wide though restricted to ORVs under 50″ in width. Connects to Meadows ORV trail and also Alcona ORV Trail. Connects to Pink Store on M-33 for food/fuel. Connects to Mio for food/fuel/motel access. Connects to McKinley for food and sometimes fuel. Connects to Mack Lake campground.
