The Experience

Staging is available at the Aquarius Ranger Station located between the communities of Bicknell and Loa. This high-mountain journey transitions from well-maintained gravel roads to rugged forest tracks, making it a premier destination for Jeeps and OHVs alike. As you climb toward 10,000 feet, you’ll be surrounded by dense Quaking Aspen groves that come alive with color in the fall. The trail opens into vast alpine meadows where you can spot elk, deer, and even the occasional black bear. While the main 20-mile loop is moderate enough for 4WD pickups and Jeeps, the technical "Shelf" sections are strictly reserved for OHVs. Be prepared for a true mountain adventure—it's always wise to bring a saw or winch for the occasional downed tree after a high-altitude storm.

Trail Safety & Ethics

Help us preserve Capitol Reef Country for future generations and ensure your own safety in the desert.
Leave No Trace Pack out everything you pack in. Stay on designated trails to protect fragile desert crusts and native vegetation. Leave what you find for others to enjoy.
Flash Floods Check the forecast. Canyons and washes can flood instantly from rain occurring miles away. Avoid narrow areas if rain is predicted in the region.
Pets Know the rules. Leash laws and pet access vary by trail and land management area. Always carry extra water for your four-legged hikers.
Emergency Be prepared. Cell service is unreliable in the backcountry. Carry a physical map, a first aid kit, and always notify someone of your planned route and return time.
