Like others have said, find a shaded spot. I was there in early September and the days were still warm and sunny. I didn’t need to reserve as the campground was only a little more than half full. Proximity to the dunes was great. If you want the creek experience then you must go in Spring...completely dry in the Fall. There was a lot of deer around and the site was plenty roomy and level. Mosca Pass hiking trail next to the campground and the trailhead is within the Great Sand Dunes National Park. It’s a nice moderate trail.
