Mills Canyon provides access to the Canadian River within a dramatic 1,000-foot canyon carved through the Kiowa National Grasslands, with a primitive campground (12 units) featuring composting toilets at the canyon bottom.

The narrow, rough Mills Canyon Road (#600) requires high-clearance vehicles and is not suitable for trailers or motor homes; water crossings may be present after heavy rains.

Dispersed camping is also available along the trail, and the area offers hiking and historical exploration of a late-1800s homestead, though cell service is unreliable and this is a remote, sparsely populated area.
