Mills Canyon Campground is a remote, free campground with 12 first-come, first-served sites situated within the scenic Canadian River Canyon at 5,160 feet elevation, offering pit toilets, picnic tables, and fire rings.

Access requires high-clearance vehicles due to the challenging 9-mile gravel road with narrow switchbacks—not suitable for trailers or RVs—and visitors must bring their own water and pack out all waste.

The location offers hiking, picnicking, and wildlife viewing opportunities in a peaceful backcountry setting with minimal crowds and no cell service.
