Great Sand Dunes National Park and Preserve

Great Sand Dunes National Park and Preserve protects 140 thousand acres in Colorado’s San Luis Valley, with 45 miles of trails leading through beautiful forests and up 13,000-foot mountain peaks. Both the park and preserve are home to the tallest dunes in North America, reaching heights as tall as 750 feet (taller than the Statue of Liberty). As a certified International Dark Sky Park, Great Sand Dunes provides awe-inspiring opportunities to experience the astronomical wonders with minimal light pollution. As one of the most ecologically diverse parks in the United States, Great Sand Dunes National Park and Preserve protects diverse landscapes, grasslands, wetlands, forests, alpine lakes, and tundra. This landscape is sacred to the Diné—Sisnaajini (Blanca Peak), located just south of the Great Sand Dunes, is one of four sacred mountains, believed to serve as a part of the boundary and protectors of the Navajo traditional homeland.
