I was here one October where the weather was above 100F during the day. The sites have absolutely no shade or cover, and are just lined up in a row next to each other with no privacy. We ended up choosing to spend more of our time at Owl Canyon (BLM campground nearby) because it was much more secluded, had better views, and offered shade. The advantages to Calico are: bathrooms with showers, water, and dump stations. However we were ok with a primitive site and did not want to feel crowded in.
