The Wichita Mountains National Wildlife Refuge in southwest Oklahoma preserves over 59,000 acres of lakes, streams, canyons, mountains, and grasslands. The refuge provides habitat for a variety of animals such as American bison, Rocky Mountain elk, white-tailed deer, and Texas longhorn cattle. To get to the refuge from I-44, take Exit 45 and follow OK Hwy 49 west about ten miles.

Very few National Wildlife Refuges have camping facilities. This one, however, has a modern campground. Doris Campground is on Quanah Parker Lake and has a total of 90 sites. There are 47 sites without electricity suitable for tent campers and RVers ($8 per night); 23 sites with electricity ($16 per night); and 20 walk-in tent-only sites ($6 per night).
