I drove here from Oklahoma to visit a ranger who used to work with me at Chickasaw National Recreation Area. Beautiful monument and trails, and the camping was superb. El Morro has nine campsites, all of which are free and first come first serve. Restrooms (vault toilets) and a water fountain are available as well. I stayed overnight on May 7 and there were 3 other campers, all quiet and friendly. The temperature got down to the mid-40s at night, which was perfect for sleeping. I loved it here!
