Things To Do


Nestled in southern Colorado, North America's tallest dunes rise over 750 feet high against the rugged Sangre de Cristo Mountains. The wind-shaped dunes glow beneath the rugged backdrop of the mountains. This geologic wonderland, containing over 30 square miles of massive dunes, became a national monument in 1932. With the passage of the Great Sand Dunes National Park and Preserve Act, resources now also include alpine lakes and tundra, six peaks over 13,000' in elevation, ancient spruce and pine forests, large stands of aspen and cottonwood, grasslands, and wetlands--all habitat for diverse wildlife and plant species.

Because the dunes and surrounding mountains are designated wilderness, this is a great place to enjoy unspoiled natural beauty in a variety of ways. Whether you play in Medano Creek, build a sand castle, slide down the dunes, go birdwatching in wetlands, or ascend a 13,000' peak, you will discover plenty of kinds of outdoor recreation for all ages.
