South of Jackson near Bryan Flats, the Willow Creek Trail is a 16 mile figure-eight loop with challenging switch-back climbs to a 7,700 feet summit and several stream crossings.
The mountain bike trailhead is located 15 miles south of Jackson near the mouth of Hoback Canyon.
To reach the Willow Creek mountain biking trailhead from Jackson Hole, head south on US189/191 to Hoback Junction and veer left towards Pinedale. Follow this for several miles until you see Camp Creek Inn on your left. Just past here you will see a large fake moose on your right and a dirt road. Take a right here and follow the dirt road, crossing over the creek and heading towards the Bryan Flats Guard Station. Before reaching the guard station, you’ll see a parking lot on the right with hitching posts. Park here and the trail takes off up the fence line.
