Explore the Dunes
Explore the tallest dunes in North America! The centerpiece of Great Sand Dunes National Park and Preserve is the 30-square-mile (78-square-km) dunefield, featuring the tallest dunes in North America. Because there are no trails, you can venture out anywhere you'd like to discover unusual insects, plants, wildlife tracks, ripples, and sand grains of every color.
Sandboarding and Sand Sledding
Sandboarding and sand sledding are the most popular activities on the dunes. Read the information on this page to have a positive, fun, and safe experience.
Splash in Medano Creek
Medano Creek is a popular seasonal stream enjoyed by all ages.
Hike Montville Nature Trail or Mosca Pass Trail
Just above the dunefield are montane woodlands of pinon and ponderosa pine, subalpine aspen and conifer forests, alpine lakes and rugged mountains over 13,000 feet (4,000 m) in elevation. The easiest access to forest in the national park is on the Montville Nature Trail and Mosca Pass Trail.
Experience the Night
Half the park is after dark! Night at Great Sand Dunes can include dunes exploration under a bright full moon, viewing thousands of stars on a clear moonless night, listening for owls along the foothills, or observing migrating amphibians on a wet night.
Hike Medano Lake and Mount Herard
Take your 4WD vehicle around the dunes and up to Medano Pass, hike to a small alpine lake, then continue to the summit of 13,297 ft (4,053 m) Mount Herard for an aerial perspective on the entire dunefield! This is a physically demanding but incredibly rewarding way to experience many of Great Sand Dunes National Park and Preserve's ecoystems, from desert dunes to alpine tundra. Watch the high-energy 40-second video to get a glimpse of this unique experience!
Available Activities
Weather
Temperatures are relatively cool all year at the park elevation 8000 ft. Conditions are most often calm, but winds can arise, especially in spring and during storm fronts. Daytime temperatures feel warmer here year round due to intense high-altitude sunlight, and mid-day summer sand surface temps can be 160 degrees F!
Plan to explore the dunes morning or evening during summer. Nights are cool in summer, and frigid in winter. Visit https://nps.
