General: 208-site campground. No hookups but sections are separated into tent-only, generators allowed, and non-generator sites (which we were very happy to see!). Only four sites can accommodate RVs up to 45 feet; otherwise, there is a 40-foot limit. 

Site Quality: All are level and have generous-sized concrete/macadam pads (except for the tent sites which are all gravel). Although the sites are close together, there is ample foliage separating them. 

Bath/shower house: I never expect showers in National Park Service campgrounds so was pleasantly surprised to find showers here (in three of the restrooms). Otherwise, the restrooms were basic but clean. 

Activities: There is a.9-mile perimeter trail that allows leashed pets and the 1.3-mile Palo Verde Trail that leads to the Visitor Center from the campground. The 21-mile one-way dirt Ajo Mountain Drive is considered the most scenic area of the park but trailers, buses, and RVs over 25 feet are not permitted on this road. There are a few short hikes off of this road. You can also drive a loop around the area, but four-wheel drive is recommended. The night sky is stunning here and there is a telescope pad. The hour-long evening ranger talk was both interesting and well-attended. The Visitor Center was also a wealth of information.

Note: As others have mentioned, when we arrived, we were instructed to leave our hoods up to discourage the pack rats. Not a problem and we didn't see any,
