This is an awesome trail to shuttle, or even a good trail to climb but really tough. Big boulders line the trail on every side throughout the ride. Steep sections have the tendency to rutted a bit. Expect hikers and riders coming up. Some riders enjoy riding up the paved Keller Road and then riding down this trail in a big loop. The Exploration Trail is a family friendly, non-motorized 4.5 mile trail with a 12% grade. This trail was designed by children along with the U.S. Forest Service personnel and other professionals.
