Camp beneath the dark skies above while surrounded by beautiful desert plants at Twin Peaks Campground or Alamo Canyon Campground. They have different amenities and offer campers a choice between modern comforts and rustic wilderness. You may see the desert dark sky subtlety illuminated by countless stars or shadows that are awakened under a full moon's glow at either campground. Songs of coyotes or the hum of a breeze may lull you to sleep. Awaken with a blazing sunrise and hike one of the trails that begin at the campgrounds.
