Very technical with extreme exposure. There are signs that say riders were killed on the trail - likely by falling over the cliff. Do not ride this from the bottom up, but use this route to finish riding Gold Bar Rim or Poison Spider (for a loop). Bring a camera and pay attention.
From Moab, take HWY 191 north to HWY 279 (Potash Rd.). Take HWY 279 south for about 3-4 miles. Trail can be accessed from one of the pullouts on the road, or at Lion's Park Campsite.
