Full-Moon Hiking, Bryce Canyon National Park, Utah
Let the moon's brilliance be your guide—that and a park ranger. Every month, for the two to three days surrounding the full moon, Bryce Canyon National Park offers nighttime hikes down a one- to two-mile trail. Though complimentary, this popular adventure requires advanced enrollment, filled on a first-come, first-served basis; hikes typically fill up within the first hour. Those afraid of their own shadows (or the hoodoos') need not apply!
