Mt. Wrightson Wilderness, AZ

Though easily accessible by road, Mount Baldy, as it's affectionately referred to thanks to its tree-free summit, is high enough, dry enough, and far enough away from civilization to offer breathtaking views of the heavens. While fully developed Forest Service campgrounds are available from 3,000 up to 9,000 feet year round, the best spot is a modest 4.5-mile hike to the summit to sleep under the stars and share the sky with the scientists at Whipple Observatory, host of Smithsonian astronomers, situated on nearby Mount Hopkins.
