There are several suggested hikes on the main trail leaving from the visitors center. The longest, a loop, is about 2 miles. It is the only one that leaves the boardwalk. It has some elevation gain. The others areally flat, with a boardwalk taking you to trees with signs explaining their significance. There is a lot of information posted around to inform curious minds, as well as some guided tours and programs from children. There are several other trails leaving or passing through this area, for those looking for a longer hike.

This HIKERS ONLY loop trail is about 8 miles, with a 700 ft elevation gain. People often only hike the Little Wild Horse part, which is a 3.3 mile one way section of the trail. It's a relatively easy trail, for all ages. The LIttle Wild Horse trail is a slot canyon set in the red rock sandstone of Southern Utah and winds its way through the San Rafael Swell. Its twisty and turny and beautiful. The Bell canyon section is actually the easier trail, but not nearly as interesting. Crowds and rain can be a problem, so be respectful and watch the weather. Rain and snow runoff are very dangerous in slot canyons. 

Be aware that during the wet season water can pool, so be prepared to maybe get a little wet. 

3.6 mile easy out and back trail. 430 ft Elevation gain. The trailhead is off  Ashton-Flagg Ranch Road along Yellowstone's South border. Ashton-Flagg Ranch Road is closed during the winter.
