This is a great little spot in Madera Canyon near Green Valley, AZ. The toilets are vault. There are picnic tables and bear proof storage lockers. I've stayed here over the last 3 years and never saw a bear. The hiking is good. The best is the birding in the canyon. Many migrate here in winter and spring. The humming birds are prolific. Using a Golden Age Pass the cost is $5. Two week limit. We camped here in a Motorhome.
