Trail Overview
Dunnigan Hill is an ideal route for offroaders of all skill levels, serving as the main scenic corridor connecting the north and south entrances of the Knoxville Off-Highway Vehicle (OHV) Area. Stretching approximately 7.8 miles through the rugged inner Coast Range, this point-to-point route reaches a maximum elevation of 2,400 feet and offers sweeping vistas of the surrounding peaks, including Mount Saint Helena in the distance. The trail is highly active with dirt bikes, ATVs, and side-by-sides, as it acts as a central spine with numerous marked and unmarked singletrack and 4WD spurs branching off in all directions.
With an easy technical rating of 2, the trail is generally smooth dirt and gravel but presents a few seasonal challenges, including mud holes that form near the Hunting Creek campsite. This site serves as the only developed campground in the Knoxville OHV area, providing a convenient staging or overnight spot for extended trail riding. Drivers can expect about 859 feet of elevation gain and 1,355 feet of descent, making for an engaging but stress-free drive accessible to most high-clearance four-wheel-drive vehicles and stock SUVs.
