Great Sand Dunes National Park

Located in south-central Colorado’s Sangre de Cristo Mountains, the Great Sand Dunes National Park and Preserve protects a stretch of huge sand dunes up to 750 feet (230 meters) in height on the eastern side of the San Luis Valley and a neighboring national preserve. On March 17, 1932, President Herbert Hoover established the Great Sand Dunes National Monument as the official name for the park. An area of 35,528 acres was protected by the original limits. As of November 22, 2000, the area was designated a national park and preserve, and on September 24, 2004, the park was officially opened. The park covers 107,342 acres and the preserve safeguards an additional 41,686 acres; the park and preserves protect a total of 149,028 acres. In 2019, there were 527,546 recreational visitors.

The sand dunes in the park are the highest in North America. More than 1.2 cubic miles of sand may be found in the dunes, which encompass an area of around 30 square miles. The valley was filled with sediments from the surrounding mountains over long periods of time. Thousands of years after the valley’s lakes dried up, the main southwest winds blew exposed sand into the Sangre de Cristos, finally producing the dune field. In the Great Sand Dunes system, the mountain watershed, the dunes, the sand sheet, and the sabkha are the four most important parts of the system. Alpine tundra, subalpine forests, montane woods, and riparian zones make up the mountain watershed’s ecosystems. The park is open 365 days a year. The park and preserve do not require reservations or limit the number of visitors, but the visitor center currently has limited capacity.

Entrances and how to reach the Great Sand Dunes National Park

Dunes tower over meadows, marshes, woods, alpine lakes, and tundra in an awe-inspiring environment. Driving south on Highway 150 or west on County Road 6 will put you in close proximity to several of the park’s highlights, such as the Dunes Parking Lot, the Visitor Center, and the Pinyon Flats Campground. Both roads are wide, well-maintained thoroughfares. Check out the map for clear information.

If you’re driving across the Rocky Mountains, don’t rely on computer mapping programs. Maps on the web and in dashboards often encourage tourists to drive on hiking paths or rudimentary 4WD roads to get to the park. To get to the main park area, many people have been trapped in the snow or at a distant trailhead. Use the map of the region displayed or any road map of Colorado.

Both Mosca (23 miles west of the park’s visitor center) and Fort Garland (25 miles east) have year-round, 24-hour petrol stations (31 miles southeast). During the months of April through October, a petrol station can be found within the Oasis Store near the park’s entrance.

By Car

One of the most typical ways to get to Walsenburg from Denver, Colorado Springs, or Pueblo is by I-25 south, then west on US 160, then north on State Highway 150. As an alternative to using I-25 from Denver, you may alternatively take US 285 south to State Highway 17 south to County Lane 6 east from Mosca for a more scenic journey (the same distance).

To get to Alamosa from Albuquerque, use I-25 north to Santa Fe, then US 285 north. It’s possible to reach Mosca from Alamosa by U.S. 160 east and north and state highway 150, or through state highway 17 north and east county lane 6.
