Welcome to Great Sand Dunes National Park
From the approach up Hwy 150, watch as the angles of sunlight make shifting shadows on the dunes; the most dramatic time is the day’s end, when the hills come into high contrast as the sun drops low on the horizon. Hike past the edge of the dune field to see the shifting sand up close; the ceaseless wind works like a disconsolate sculptor, constantly amending the landscape.
Most visitors limit their activities to the area where Medano Creek divides the main dune mass from the towering Sangre de Cristo Mountains. The remaining 85% of the park’s area is designated wilderness: not for the unfit or fainthearted.
