The Great Sand Dunes are the tallest sand dunes in North America, next to diverse grassland, wetland, and alpine ecosystems.
When you visit, hike up the dunes and slide down on a sandboard or sand sled.
Lt. Zebulon Pike was the first recorded American Explorer ( January 1807) to cross the Sangre de Cristo Mountains to the Great Sand Dunes. Pike and his men were exploring the Louisiana Purchase Territory under orders from President Thomas Jefferson.
This is one of the quietest parks in the country, due to its arid climate, the topography, and a location far from flight paths.
