Cottonwood Campground is one of the best places in Joshua Tree National Park for stargazing and wildflower viewing. Easy access from Interstate 10, makes it a popular stopover for travelers. Visitors 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. Cottonwood Campground is at an elevation of 3,000 ft. and has little shade from vegetation; however, there are picnic shelters that provide shade at each site. There are no electric, water or sewer hook-ups available at individual campsites; drinkable water spigot is located nearby. There is no overflow parking. Check in at Cottonwood Visitor Center, right near the campground.
