Morning Glory Natural Bridge is a huge natural bridge and an incredibly popular hiking and rappelling spot at the end of a scenic side canyon of Grandstaff Canyon. Spanning 243 feet, it is the sixth longest natural rock span in the United States, and an incredibly impressive sight. You can go beneath the bridge to marvel at its beauty and take photographs while also cooling off in the shade. There is shallow pool of water under Morning Glory Natural Bridge, which is what makes it a bridge as opposed to an arch. This is a fantastic place to sip some water and relax before returning to the trailhead.
