The Chickasaw NRA is located in southern Oklahoma on the eastern shores of the Lake of the Arbuckles about 10 miles east of Interstate 35 southwest of Ada and Sulphur and was the first national park in the state of Oklahoma. It attracts 3.4 million visitors a year which makes it one of the most popular in the nation for its size.

The Park has had three designations since its inception in 1902 as Sulphur Springs Reservation. Subsequent desinations include Platt National Park, in 1906 and its current name in 1976. It was called "Peaceful Valley of Rippling Waters" by First Nation visitors.

Activities include boating, camping, fishing, hiking, hunting, swimming in the Little Niagara Swimming Area and, of course, enjoying nature.
