Turner Falls, Natural waterfall in Arbuckle Mountains, Oklahoma, United States

Turner Falls is a waterfall in the Arbuckle Mountains of south-central Oklahoma that drops 77 feet (23 m) into a natural swimming pool. Water cascades over a rock ledge into Honey Creek, forming a clear pond surrounded by tall limestone walls.

Scottish immigrant Mazeppa Thomas Turner discovered this waterfall in 1878 after settling in the area with his Chickasaw wife Laura Johnson. In the 1930s university professor Ellsworth Collings built a stone castle as a summer residence on the slope above the falls.

The falls are named for Mazeppa Thomas Turner, a Scottish immigrant farmer who settled here in 1878 with his Chickasaw wife Laura Johnson and found the waterfall. Recreational use of the site began in or before 1868, when it lay in Pickens County, Chickasaw Nation. The falls now sit inside Turner Falls Park, run by the city of Davis, where the cascade empties into a natural swimming pool that draws summer visitors.

The grounds open at different times depending on the season, with summer hours from May through September and winter hours from October through April. Visitors reach the swimming area by walking a short trail from the entrance, though you should take care on slippery rocks after rain.

At 77 feet this waterfall shares its height with Natural Falls State Park, and both are considered the tallest waterfalls in Oklahoma. The stone castle above the falls originally served as a professor's private retreat and is now open for visitors to explore.
