Devil's Bridge
This is a very popular out and back trail in the Sedona, AZ area. This is the largest natural bridge in the Coconino National Forest. You will often need to park quite a ways from the actual trail head and will encounter numerous hikers even during the warmer months. The hike is easy except for the last ~2/10 of a mile to the bridge where it is moderate. The bridge itself is great for pictures and is much wider than the pictures make it look.
