Navajo Knobs is a sandstone summit viewpoint above Fruita, reached by continuing beyond the Hickman Bridge and Rim Overlook route. It is a strenuous hike, not a roadside stop: the summit is 4.7 miles one way with 1,620 feet of elevation change, about 9.4 miles round trip. Start at the Hickman Bridge trailhead on Highway 24 and follow the route past Rim Overlook. A pit toilet and parking are at the trailhead, but carry all the water you need; none is available along the trail. Parking at many park trailheads fills by 9 a.m., and the exposed climb is a much better fit for a cool part of the day than a hot afternoon.
