Experience North America's tallest dunes, seasonal creek wading, sandboarding, and incredible dark-sky camping at this unique national park.
Great Sand Dunes National Park features the tallest sand dunes in North America, rising against the rugged Sangre de Cristo Mountains. The 30-square-mile dunefield provides a desert-like landscape surrounded by alpine lakes, forests, and wetlands. Visitors can hike anywhere on the open dunes, as there are no designated trails on the sand. During late spring and early summer, Medano Creek flows at the base of the dunes, creating a wide, shallow beach environment for wading. Camping at the park is a primary draw for visitors. The main Piñon Flats Campground offers immediate access to the dunefield and unobstructed views of the night sky. The park is recognized as an International Dark Sky Park, making it an excellent location for stargazing. Backcountry camping directly on the dunes or along the 4WD Medano Pass Primitive Road provides an immersive outdoor experience. Daytime activities center around hiking, sandboarding, and sand sledding.
