Jeep trail that has sand and many step ups. Follow the signs and cairns. Follow the blue dots, or the Gold Spike jeep trail after you reach the rim. You can connect this trail to Poison Spider or Portal Trail for a one-way shuttle.
From Moab, take HWY 191 north to 5(?) miles. Trail is on the right (west).
