"Known for an otherworldly landscape of vibrant red-rock hoodoos—the largest concentration of hoodoos in the world—this Gold Tier Dark Sky Park offers some of the darkest skies possible. Visitors can join a ranger-led Night Sky Telescope Program (runs Memorial Day through Labor Day) and attend an Astronomy Festival in June, which is considered the best month to see the Milky Way; planning around a new moon (or observing before moonrise/after moonset) further enhances visibility." - Evie Carrick Evie Carrick Evie Carrick is a writer and editor who’s lived in five countries and visited well over 50.
