Witness the surreal sight of North America's tallest sand dunes nestled against the rugged Sangre de Cristo Mountains. This unique landscape invites exploration unlike any other park. Hike up the massive dunes for panoramic views (and a tiring workout!), then experience the thrill of sandboarding or sledding back down. In late spring/early summer, the seasonal Medano Creek flows at the dunes' base, creating a popular natural beach perfect for splashing and cooling off. It’s a geological marvel offering fun recreation and striking visual contrasts.
