The Under the Rim Trail is the premier backpacking route in Bryce Canyon National Park. Although it seldom strays more than a few miles from the park road, its position below the rimrock lends it a backcountry-like solitude. The hoodoos and cliffs along this trail are less spectacular than those in the heavily traveled northern reaches of the park, but those who hike here will seldom run into other visitors. Several connecting trails link this route with the road, allowing backpackers to select a route of almost any conceivable length. For overnight trips travelers must register in advance for one of the designated campsites that appear on the map accompanying this description. Once set, you cannot change your itinerary (written on your permit).
