4. Little River Canyon, Alabama
Little River Canyon is the deepest canyon east of the Mississippi River. The water plunges into the canyon, flowing for 12 miles, settling into a series of beautiful swimming holes bordered by the canyon’s lovely red sandstone. These pools are a favorite haunt of merrymakers in the summer.
Little River Canyon is an exceptional natural swimming pool because it is the only river that forms and flows for almost its entire length on the top of a mountain. It offers a wide variety of activities besides the natural pool, including an informative hike, enjoying picnics, learning about and exploring the Wildlife Management Area, and more.
