The Great Sand Dunes National Park and Preserve encompasses the highest sand dunes in North America and the surrounding area. Originally a national monument, Congress approved the purchase of additional acreage and redesignated the area a national park.
More information about the formation of the dunes on the eastern side of the San Luis Valley in southern Colorado and other visitor information can be found at the park's website. The dunes are about 20 miles from Blanca on the west side of the Sangre de Cristo Mountain Range.
