Point of Interest
Constrained by a deeply cut chasm during high water, the Boulder River flows over a 100-foot precipice, creating the spectacular Natural Bridge Falls. At low water, the river used to flow under a natural rock bridge, but in July 1988, the bridge that gave the area its name, collapsed.
Paved pedestrian trail provides great views and interpretive geologic information.
