North of Moab, the Gemini Bridge route is a 13.5 mile one-way route along a rough, old jeep road. When ridden west to east, there are great descents (total vertical of 1,400), but save energy for the sand traps at the end in Little Canyon. Best done with a car shuttle. The route is blazed with brown carbonite signs. Keep an eye out for Bighorn Sheep.
