Great Sand Dunes National Park and Preserve

Great Sand Dunes National Park and Preserve conserves an area of large sand dunes that are up to 750 feet tall. The park contains the tallest sand dunes in North America. The dunes cover an area of about 30 sq miles. The park also preserves alpine lakes, mountains and tundra. Accessing the dunes requires walking across the wide and shallow Medano Creek. The park is popular for hiking, sandboards and sand sleds.
