Great Sand Dunes National Park — The Tallest Dunes in North America

In the middle of a high desert valley in Colorado, an ocean of sand rises out of nowhere and piles itself into the tallest dunes on the continent. They stand more than seven hundred feet high, glowing gold against a wall of snow capped peaks, and at their feet a strange seasonal creek pulses with waves in the spring. It is one of the most surprising landscapes in America, a mountain of sand where you least expect it. Welcome to Great Sand Dunes National Park. Filmed May 2026.
