The Klondike Cliffs Trail is a modest climb, but isn't too technically difficult. It's a good trail for someone who's in good shape, but is inexperienced in mountain biking.
Chad ascends the slickrock portion of the trail.
The trail climbs 800 feet in four miles. Give yourself about three hours, including sightseeing. Dinosaur footprints are found in newly exposed areas of Kayenta sandstone. The trail begins with just over a mile on modestly rough double-track with a few short sand digs. At the end of the road is a short section of single-track that climbs to the border of Arches National Park.
