Covering a vast swathe of southwest Oklahoma, the wonderfully wild Wichita Mountains Wildlife Refuge lies just to the north of Lawton. Founded in 1901, it preserves diverse landscapes and countless species of fauna and flora.

Very mountainous, it is home to everything from steep ravines and sweeping valleys to flower-filled meadows and forests. Dotted about its confines are 13 artificial lakes, as well as plenty of scenic hiking trails and rock climbing routes. Due to the outstanding beauty on show, it is a splendid place to go camping and fishing, with some excellent bird and wildlife watching on offer.

While much of the park is open to the public, more than half of it is an untouched wildlife refuge. On guided tours, visitors can spot elks, armadillos, otters, and the breathtaking bison, which now number more than 650 in total.
