Alum Cove Natural Bridge


1.1 Miles


A very unique natural stone bridge located in the Ozark National Forest. The 1.1 mile easy/moderate trail offers access and views of the arch. The arch of the Natural Bridge spans 130 ft. and is approximately 20 ft. wide. After viewing the arch you can either return back or continue along the looped trail. The looped trail will descend below the arch, cross a small stream and follow the bluffs and eventually return back to the Natural Bridge.
