The trail is mapped here as a one-way from south to north, but it’s good in either direction, and you can ride any distance out and back if you don’t have a vehicle shuttle. The trail is all singletrack, with a good blend of non-technical climbing and smooth downhill. The variety of terrain and scenery make it perfect for a relaxed-pace, all-day ride.

Though famous for being on the edge of the Grand Canyon, the majority of the trail is concealed in the forest. Most of the canyon views are at five “points” of land that protrude into the gorge. At these points, the trail passes dramatically, but not dangerously, close to the rim. The grandest views are had by dismounting and walking to an airy outcrop on the edge.

Canyon vistas are indeed the highlights, but the forest sections are far from disinteresting. The stretches between overlooks wind through sunny pine forest and dip through shady glens with aspen glades and flower-filled meadows.

Though the Rainbow Rim Trail is popular among mountain bikers, getting there is not easy, and you should expect a backcountry experience when you arrive. It requires miles of travel on rough dirt roads, with no services nearby and limited cell service. To make the most of your time, you should plan to camp at least one night. Vehicle camping is allowed for free at multiple access points along the trail. The best camp spots are at either end of the trail or at Locust Point, which is approximately the midpoint. Be sure to respect any road closures and fire restrictions that may be posted, and respect the environment by minimizing impact where you camp.
