Springs, streams, and lakes are the attractions at Chickasaw National Recreation Area, the first national park in Oklahoma. Visitors find camping, boating, fishing, swimming, hiking and nature walks. The Travertine Nature Center and its adjacent environmental study area offer exhibits and ranger-led programs, and the wider Chickasaw Cultural Center just outside the park is the best place to understand the nation that gives the area its name.
The park sits in the foothills of the Arbuckle Mountains near Sulphur, Oklahoma, roughly 80 miles south of Oklahoma City. It was established in 1902 as Sulphur Springs Reservation, a federal protection of the local mineral springs, and is one of the most heavily visited parks for its size in the National Park System — about 1.5 million visitors a year. The peak season runs from Memorial Day to Labor Day, with activities focusing on water recreation at Little Niagara on Travertine Creek and on the bigger Lake of the Arbuckles and Veterans Lake. January and February see the fewest visitors.
