Navajo Rocks - West (Big Mesa, Big Lonely, Coney Island)
The western half of the Navajo Rocks riding area consists of three connected trails:  Big Mesa, The Big Lonely, and Coney Island. Taken together, they form a 10-mile route that can be ridden as an 11-mile loop (by including Middle Earth, a trail that cuts across the loop), or as part of the full Navajo Rocks loop that includes Rocky Tops and Ramblin. The west half-loop can be done by intermediate riders; the full loop is for upper-intermediates or better.

Getting there, East Parking:
From I-70 and Crescent Junction, drive south on US-191 for 20 miles. If coming from Moab, drive about 9 miles north of the Colorado River on Highway 191. Turn west on Highway 313. At mile 5.3 (shortly after you pass the view area), there's a fenced trailhead on the right. This is where the loop crosses the highway. Park here to start at the east end of Rocky Tops or Ramblin.
West Parking: Proceed on Highway 313 as above, but at mile 6.1 keep driving straight as you pass the main parking area. At mile 6.4 just as you reach the top of a hill, look for a gravel turn on your right just as you pass through the cut in the hill. Go 100 feet and park by the trail sign. Ramblin and Big Mesa share their first 1/4 mile of trail. Middle Earth is across the road.
