Cold Brook Canyon Trail
Starting on the west side of U.S. 385, 2 miles south of the visitor center, this 1.4-mile (one-way), mildly strenuous hike runs through an active prairie-dog town, the edge of an area burned by a controlled fire in 1986, and through Cold Brook Canyon to the park boundary fence. Experienced hikers can conquer this trail and return to the trailhead in an hour or less, but more leisurely visitors will probably need more time. Moderate.
