About this landmark
High Dune, located in the mesmerizing San Luis Valley of southern Colorado, is one of the most striking natural highlights within the Great Sand Dunes National Park and Preserve. Towering at approximately 750 feet, High Dune offers an awe-inspiring contrast against the rugged backdrop of the Sangre de Cristo Mountains. This unique clash of towering dunes and snowy peaks showcases a rare and dramatic landscape that draws outdoor enthusiasts and nature lovers alike.
What sets High Dune apart is the sheer immensity of sand—a natural phenomenon created by thousands of years of wind erosion and deposition, making it the tallest dune within this expansive field covering 30 square miles. This area provides not only a visual feast but also a remarkable playground for adventure activities, from hiking to sandboarding.
The park is home to diverse ecosystems, including medano creeks, alpine lakes, and unique flora and fauna adapting to both arid and alpine environments. Established as a national park in 2004, the area not only preserves the dunes' delicate beauty but also bears witness to the historical footprints of Native American tribes known to have inhabited the region. Experience the lingering whispers of the past as you tread upon these ancient grains of sand.
