Great Sand Dunes National Park

Established as a National Monument in 1932 and designated as a National Park in 2004, Great Sand Dunes protects 149,028 acres of diverse landscape. The park features North America's tallest sand dunes, rising to 750 feet against the backdrop of the Sangre de Cristo Mountains.

Beyond the dunes, the park encompasses grasslands, wetlands, conifer and aspen forests, alpine lakes, and tundra. This remarkable diversity of ecosystems supports a wide range of plant and animal life, creating a unique natural laboratory of adaptation and survival.
