You won't be disappointed if you make the trek to Double O Arch from Devils Garden trailhead. Once you get past Landscape Arch the crowds disappear, and the views get incredible along the trail. Once at Double O, to get that famous shot, you'll have to climb through the lower "O" and walk around on a rock ledge. Breathtaking views. Dark Angel is another 0.5 mi. farther, but only worth it if you have the time. You can see it well right from near Double O. 4.5 mi. RT hike to Double O Arch.
