The 603.1 sq. km. (232.9 sq. mile) Great Sand Dunes National Park and Preserve contains the tallest sand dunes in North America and is located in south-central Colorado. According to NPS monitoring data, Great Sand Dunes is one of the quietest NPS sites and enjoys extremely pristine night skies owing to its remote location. Furthermore, the Park is also well-known for the seasonal Medano Creek and beach created at the base of the dunes. Additional attractions at the Park include: the backcountry Medano Pass Primitive Road winds through a canyon toward the Sangre de Cristo mountains and ample trails which lead to forests, wetlands, and alpine lakes.
