Glory Hole has many recreation trails, a little less than 15 miles all together. Buck Brush Loop and Heron point are easy trails, Tower Climb is as steep as it sounds.
Natural Bridges can be accessed from Parrotts Ferry road. It is open to foot traffic only and is a somewhat steep trail down to Coyote Creek. In the summer bring your inner tube to float down the river and under the cave like natural bridge.
Other trails in the area: Carson Creek, Gold Rush, Frontier, Peoria Wildlife Mountain and Ridge Trail (Horses allowed), and Table Mountain.
