Great Sand Dunes National Park

Great Sand Dunes National Park and Preserve is a national park in south central Colorado, containing North America's tallest sand dunes, which rise over 750 feet against the rugged Sangre de Cristo Mountains. The park encompasses over 30 square miles of massive dunes, along with alpine lakes, tundra, six peaks over 10,000 feet, ancient spruce and pine forests, and wetlands. Originally established as a national monument in 1932, it was designated a national park in 2004 after significant expansion to protect the watershed surrounding the dunes.

The dunes were formed by wind-blown sand deposited over thousands of years from the San Luis Valley floor. The park sits at an elevation of about 8,200 feet and enjoys a semi-arid climate. Summer daytime temperatures rarely reach 90°F (32°C), with highs in the 70s-80s°F (21-27°C). Summer nights are surprisingly cool, often dropping into the 40s°F (4°C). Afternoon thunderstorms are common in July and August, and visitors should leave the dunes promptly if lightning threatens. Winter brings cold temperatures with highs in the 20s-40s°F and snow possible. Spring can bring strong winds. The San Luis Valley is known as the "Land of Cool Sunshine" with abundant sunshine year-round.

By Plane

The nearest airport is San Luis Valley Regional Airport in Alamosa (ALS), with commuter service to Denver on Boutique Air, offering about three flights daily each way. Denver International Airport (DEN) is approximately 150 miles to the northeast as the crow flies, though the drive is considerably longer due to the mountain terrain.

By Car / Road

The park is accessed via a side road from Colorado SR 17 between Poncha Pass and the town of Alamosa. Another route is via US 160, crossing a high pass through the Sangre de Cristos between Alamosa and Walsenburg, then onto SR 150. Alamosa is about 230 road miles from Denver, though the straight-line distance is considerably less due to the rugged Sangre de Cristo Mountains. The road is paved but winding.

Once at the park, the visitor center is the main starting point. The dunes themselves are a very short distance from the visitor center, accessible by a well-marked path. Beyond the dunes, there are no marked trails — you simply wander among them. Windhorse Transportation offers tours and taxi service in the Crestone/BACA and Moffat area. A car is essential for reaching the park and exploring the surrounding area.
