Cottonwood Group Campground is one of the best places in Joshua Tree National Park for stargazing and wildflower viewing. The group campground is part of the main Cottonwood Campground and has three sites that are by reservation only. It is one of three group campgrounds in the park and the only campground that lies in the southern section. Travelers who enjoy warm, dry winters flock to Joshua Tree from October through May, when temperatures reach between 70 to 90-degrees during the day and drop to 40 to 60-degrees at night. Summer is the park's off-season due to the uncomfortably high desert heat.
