Northwest of Sedona, the 6 mile Deadmans Pass Loop combines several excellent singletracks.
To reach the mountain biking trailhead from uptown Sedona, head west on SR89A for 3.5 miles to Dry Creek Road. Turn right heading north for several miles. Watch for Dry Creek Road veering to the right and becoming a dirt road. Follow this dirt road. After about 100 feet is a small parking area on the right for purchasing Red Rock Passes. Continue on for about 0.3 miles to the top of a short rise and look for a parking area on the left.
From the parking area, follow the jeep road in the parking area north for about 25 foot and look for the start of the unsigned Lost Watch Trail. The Lost Watch Trail descends onto a slickrock heading north and ascends back up to its summit. Near the summit, the trail becomes very rocky and rough as it winds through chaparrell brush. Next, it descends down to a dry wash and runs parallel through sand before crossing and ending at Long Canyon Road. Turn right heading east on Long Canyon Road for about 0.5 miles to Long Canyon Trail parking area on the left.
Turn north onto the Long Canyon Trail following a narrow parked dirt doubletrack for about a mile. Just before the Wilderness boundary, turn left heading west on the Deadman Pass Trail. The tral climbs for about 0.5 miles before a fabulous rolling descent over the next mile under a single power line. Follow the trail under the power line to the end at Boyton Canyon Road. Turn left onto Boyton Canyon Road heading south.
At the intersection with FS152, turn right onto the dirt road for about 0.5 miles to the Fay Canyon trailhead parking area. Just past the main parking area on the right, turn left on FS9586 (Fay Canyon overflow parking area). Follow this rough narrow jeep trail for about 0.4 miles and turn southwest onto signed Cockscomb Trail. Follow the Cockscomb Trail as it rolls under a power line for about a mile.
Turn left onto the Dawa Trail and follow back to Boyton Canyon Road. Turn right and follow Boyton Canyon Road east a couple miles back to Dry Creek Road.
