McAdams River Access Campground is a free, primitive single campsite within Tishomingo National Wildlife Refuge's Wildlife Management Unit, offering a picnic table and fire ring suitable for cars, vans, and pickup trucks (trailers up to 20 feet).

Located on the Washita River with a small turnaround area, it provides a quiet, tree-shaded setting ideal for fishing and wildlife observation, though heavy mosquito populations require insect repellent and internet connectivity is limited.

Camping is first-come, first-served with a 7-night maximum stay per visit.
