"Fisherman, boaters, and swimmers alike will find what they are looking for at Chickasaw National Recreation Area in Oklahoma. Located in the foothills of the Arbuckle Mountains, a quarter of Chickasaw’s almost 10,000 acres are covered by water. Visitors find ample opportunities to cool down in the natural springs, streams, and lakes of the park. Although popular and often crowded, Little Niagara is a great swimming hole to spend an afternoon at." [Travel+Leisure]
