Poison Spider Mesa
This route has it all: fun obstacles and great scenery. It's common to drive the first portion heading to Golden Spike, but be sure to take the loop, as it offers slickrocks, a sandy hill to play on and an overlook you won't want to miss. Play with caution and be aware of mountain bikers in the area. If you want to get sidetracked for a bit, check out Barney's Overlook.
Drive north from Moab on Highway 191. About 1.4 miles after crossing Colorado River, turn left on Hwy. 279. Follow it south 5.9 miles and turn right into well-marked parking lot.
