Bighorn National Forest ATV riding guide

With more than 1,200 miles of roads and trails across 1.1 million acres of public land, Bighorn National Forest offers something for every off-road rider—from scenic routes to technical challenges.

Popular trails open to off-highway vehicles (OHVs) include:

• Bald Ridge Trail (#402): A challenging ride that rewards experienced riders with mountain meadow views and high-altitude riding.

• Penrose Park Trail (#028): This route leads to the historic Penrose Guard Station and offers access to picnic spots in Penrose Park.

• Parallel US 16 Trail (#117): Looking for a more scenic alternative to the highway? This trail runs alongside US 16, offering beautiful forest views.

Be sure to stay on designated routes—it's key to protecting the land and staying safe. Trails are clearly marked, and most are designed to minimize environmental impact. Your ATV must display a valid Wyoming ORV permit decal. Learn more at the Wyoming State Trails Program.

To avoid getting off track, download the official Motor Vehicle Use Map (MVUM) from the U.S. Forest Service. The Avenza Maps app is a popular tool that works offline and allows you to track your route with GPS—no cell service needed.

When selecting trails, look for those marked as open to vehicles 50 inches wide or less for true ATV access.

Many riders choose to stay in Sheridan while exploring Bighorn National Forest. The city offers easy access to the park along with lodging, restaurants, and supply stops. Of course, camping is also available throughout the forest if you want to stay closer to the trailheads.

If you're planning an off-season trip, keep in mind that many roads and routes are closed during the winter and spring months due to wet or snowy conditions. Most years, the best riding season runs from May through October—though that can vary depending on snowfall and elevation. It's always a good idea to check current closures and trail conditions before you travel.
