National Park


In this high mountain valley are the tallest dunes in North America, flanked by some of the highest peaks in the Rocky Mountains. The park and preserve protects much of the Great Sand Dunes' natural system, including alpine tundra and lakes, forests, streams, dunes, grasslands, and wetlands.


Great Sand Dunes National Park and Preserve is open 24 hours a day, all year. In winter, the Visitor Center hours are 9:00 a.m. to 4:30 p.m. daily, except for federal holidays, when the building is closed. In spring and fall, the Visitor Center is generally open 9-5; longer hours may exist as staffing permits. Summer hours at the Visitor Center are generally 9-6. Call ahead at (719)378-6399 for specific hours on the days you plan to visit.

Since the campground is self-registration and first-come, first-served, you may self-register for a site 24 hours a day when sites are available.
