Turner Falls & the Arbuckles — Oklahoma's Tallest Waterfall, Castle Ruins & Swimming Holes
A swim-and-scramble day trip into the ancient Arbuckle Mountains, one of the oldest exposed mountain ranges in North America and an easy 95-minute run up I-35 from Dallas. The centerpiece is Turner Falls, a 77-foot cascade — the tallest waterfall in Oklahoma — that drops into a wide, cold natural swimming pool at the base of a rugged canyon. Above the falls, the 1930s stone ruins of Collings Castle are built straight into the bluff and can be freely explored, while Honey Creek carves a string of shallow swimming and wading areas through the park, and two small caves wait to be scrambled into near the falls. It's a day of cool water, warm rock, and a castle in the hills, with the option to load up on famous roadside fried pies and Oklahoma-made chocolate on the way home.
