If you go by jeep, you can cut off half the distance to Devil's Bridge. If you hike it, its 2.0 miles one way from the trailhead, all uphill. To reach the trailhead by car, take Dry Creek Road north from Highway 89A near the western edge of Sedona. Follow Dry Creek Road to its end and turn right. The pulloff for parking is about 400 yds along this road on your right. The trail you take first is the Chuck Wagon Trail north as far as the jeep road. Then you follow Devil's Bridge Trail to its end.
Best time of the day to go is early morning while it is still cool and before the jeeps arrive at the Devil's Bridge Trail trailhead. Once at Devil's Bridge you can view it from below or, if you desire, climb up to view it from above. The trail to the top of the arch is rough with steep and irregular steps. However, the views from the top of the arch are great!
