Great Sand Dunes National Park and Preserve, USA

The Great Sand Dunes National Park and Preserve boasts 230-metre sand dunes – the tallest in the United States – that cover approximately 78 square kilometres. But these towering sand dunes are just one feature of a Colorado landscape that includes conifer forests, alpine lakes and wetlands. The park and preserve even encompasses stretches of tundra at higher elevations, where it is close to the base of the Sangre de Cristo Mountains.
