The parking lot is located 12.2 miles west of Vernal, UT, halfway past MM 129. There is a dirt road on the north side of the road where it will take you to a small dirt parking lot. Last time I went, there was a wheel nailed to the fence just before the parking lot.
This is a very typical trail on the orange-red dirt of the area. You can probably do some lapping of both Corkscrew
and Racetrack for longer rides.
