A beautiful little campground of solitude was found if you drove on just past the Mills Canyon Campground. Not very much available in terms of hiking, but what there was went along the Canadian River, and yielded some interesting, crumbled old structures. Definitely take the time to read a little bit of the history once you have a signal again! Campfires weren’t allowed while we were there, but they are allowed when the fire danger isn’t so high. There are vault toilets (which were well maintained), but no running water. There is no cell service. Bring trash bags, as there are no trash cans or dumpsters. No bear lockers, though there are bears in the area. Recommend 4 wheel drive to access the Canyon itself. Many of the primitive roads have been closed to motorized vehicles, but still make for a nice hike! We could hear owls every night, and saw a mountain lion one morning.
