Trail Overview

This route trail heads from the Mount Trumbull Schoolhouse approximately 50 miles south of St. George, Utah. This is a fun and informational adventure into the Grand Canyon National Park with an overlook approximately 1500 feet over the Colorado River. Along the way, you will pass fantastic scenery, including cinder cones, lava flows over ridges, and many other geological wonders. You will also pass through property owned by the Bar 10 ranch, so please be respectful of the area and watch your dust as you go by the ranch house as they host visitors in the wagons. If your looking to add some adventure to your trip, look them up for an overnight stay. One of the reasons to consider trailhead at the schoolhouse is there are no services south of St. George. By trailering to the schoolhouse, you can carry additional gas and provisions. When traveling in the Arizona strip, it is highly recommended that someone in the group carry a GPS communicator.


The northern portion of the road is maintained and is primarily a standard gravel road found in most country areas. South of the Bar 10 airport the route turns slightly more primitive with larger rocks, some steeper climbs and possible washed out areas.
