Great Sand Dunes National Park Things to Do

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. In warmer months, watch for one of 7 species of endemic insects, found nowhere else in the world, that are specially adapted to the extreme environment here.

One of the two tallest dunes in North America, pyramid-shaped Star Dune rises 741 feet (225 m).

Hidden Dune is one of the two tallest dunes in North America, located in a remote part of the dunefield of Great Sand Dunes.

The most popular to climb of the tall dunes at Great Sand Dunes

Medano Creek is a popular seasonal stream enjoyed by all ages.

Medano Pass was likely the historic route used by Zebulon Pike in January 1807 as he led an expedition to explore this region. Today Medano Pass is primarily traveled by 4WD vehicle, on a rough 22-mile road connecting Great Sand Dunes with the Wet Mountain Valley and Colorado State Highway 69. Passable only in the warmer months and only with high-clearance 4-wheel-drive vehicles, it gives access to Medano Pass (elevation 10,040’) and Great Sand Dunes National Preserve.

Just above the dunefield are woodlands of pinon and ponderosa pine, and subalpine aspen and conifer forests. The easiest hiking access to forest in the national park is in Mosca Pass, on the Montville Nature Trail and Mosca Pass Trail. On these trails, you are walking in the footsteps of Pleistocene mammoth hunters, indigenous tribes, diverse settlers, American explorers, and 19th century African American Buffalo Soldiers.

Sand Creek Basin is part of the alpine watershed of Great Sand Dunes National Preserve. A longer drive and hike is required to reach these lakes and peaks, but the mountain scenery is worth the effort. Check with a ranger for conditions before travel. Snow may block these trails from November into June.

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.

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.
