Great Sand Dunes National Park and Preserve Overview
Great Sand Dunes National Park and Preserve protects about 149,028 acres of dunes, wetlands, grasslands, forests, alpine lakes, and Sangre de Cristo Mountain terrain in southern Colorado. The park recorded 432,498 recreation visits in 2025, with most visitors drawn first to the tallest dunes in North America and the seasonal flow of Medano Creek. The landscape changes dramatically with wind, snowmelt, temperature, and time of day.
Most first-time visitors spend time on the main dune field, where there are no fixed trails and distance is harder than it looks. The park also has forested hikes, alpine routes, four-wheel-drive access along Medano Pass Road, and backcountry zones that feel very different from the busy day-use area.
Great Sand Dunes was first protected as a national monument on March 17, 1932, and became a national park and preserve on September 13, 2004. The park protects a rare meeting of desert-like dunes, mountain watersheds, wetlands, and cultural history tied to Indigenous travel, ranching, and conservation.
Great Sand Dunes National Park and Preserve Hiking and Backpacking
NPS Hiking information covers High Dune, Star Dune, Mosca Pass, Montville Nature Trail, and Medano Creek area walks. Hiking on sand is slow and exposed, and summer surface temperatures can become painful or dangerous for bare skin and pets.
NPS Backpacking guidance is useful for designated dune and mountain zones with permits. Dune camping can be spectacular under dark skies, but visitors need to plan for wind, sand, lightning, cold nights, water access, and the physical effort of carrying gear across soft sand.
Things to Do in Great Sand Dunes National Park and Preserve
Hiking the dunes is the signature thing to do in Great Sand Dunes National Park and Preserve. High Dune, Star Dune, and open dune routes have no fixed trail, so visitors should plan for slow sand travel, wind, heat, and strong sun.
Sandboarding and sledding are major visitor activities and work best with proper boards rented outside the park. Medano Creek is another seasonal highlight, especially during spring and early summer flows.
The park also has mountain, forest, and preserve routes beyond the main dune field. Mosca Pass, Montville Nature Trail, Medano Pass Road, alpine lakes, and backcountry zones add hiking and backpacking options for visitors who want more than the dunes.
Stargazing, photography, wildlife viewing, camping at Pinon Flats, and sunset visits help make the park a strong overnight destination.
Great Sand Dunes National Park and Preserve Camping and Lodging
Use NPS Camping details for Pinon Flats Campground, which is reservable seasonally, and for backcountry permit planning in dune and mountain zones. Wind, lightning, and hot sand are important hazards.
