Permit required for vehicle camping at the High Spur campsite. Camping is not permitted in Horseshoe Canyon. Easy to canyon rim, extremely difficult into canyon. It's packed dirt and loose sand with a few short rocky sections all the way to rim of Horseshoe Canyon. The road down into the canyon is rocky, steep, narrow, and technical four-wheeling.
Most people stop at the rim of canyon and walk the road into canyon.
Grazing is allowed in Glen Canyon NRA, so watch for cattle on the road. Flat except for the drop into the canyon, easy going in most places with a few stretches of loose sand in first 10 miles and near the canyon rim. Side roads to High Spur Camp and up Deadman's Trail are also excellent for mountain biking. Get a great view of Cleopatra's Chair which really looks like a chair from here. Grazing is allowed in Glen Canyon NRA, so you could have a cow in camp.
