Great Sand Dunes National Park and Preserve is located in the easternmost parts of Alamosa County and Saguache County, in Colorado. Originally designated Great Sand Dunes National Monument, Great Sand Dunes National Park and Preserve was created by an act of the United States Congress on September 13, 2004. The park contains approximately 85,000 acres (340 km², 130 mi²). The park contains the tallest sand dunes in North America, rising about 750 feet (230 m) from the floor of the San Luis Valley on the western base of the Sangre de Cristo Range, covering about 19,000 acres (77 km²). They are perhaps 12,000 years old. The dunes were formed from sand deposits of the Rio Grande and its tributaries, flowing through the San Luis Valley. The park also contains alpine lakes and tundra, six peaks over 13,000 feet (3,940 m) in elevation, ancient spruce and pine forests, large stands of aspen and cottonwood, grasslands, and wetlands — all habitat for diverse wildlife and plant species.

Head towards the San Luis Valley and within an hour and a half you will find the Great Sand Dunes National Park. Spend an afternoon at the Dunes and attempt to climb to the tops. Don't forget your sunscreen! In May and June, bring a swim suit. Water flows like a river right through the base of the Dunes.
