Great Sand Dunes · Mile 01 · The Story

A desert that has
no business being here.

Colorado is not a place most people associate with sand dunes, which is exactly what makes this park so disorienting in the best way. Wind sweeping across the San Luis Valley for millennia has piled sand against the base of the Sangre de Cristo Mountains, building the tallest dune field in North America, with Star Dune topping out around 750 feet, all of it sitting at 8,200 feet elevation and ringed by peaks over 13,000 feet.

Every spring, snowmelt from the mountains creates Medano Creek along the dune field's edge, a shallow, surge-flowing stream that behaves almost like a tide pool, rising and falling in pulses that kids can wade in and adults inexplicably cannot stop watching. It usually dries up by midsummer, so the timing matters if that's the draw.

Come for the surreal scale of the dunes. Stay for the night sky, among the darkest certified anywhere in the country. Read the story, trust the live data above for what is open today, and when you leave, collect the stamp.

Best Things to Do in Great Sand Dunes

Six ways to spend your time, from wading a surge-flow creek to sandboarding down a 700-foot dune.

Wade Medano Creek

A shallow, pulsing stream at the base of the dunes, usually flowing from April through June, gone by midsummer.

Families · spring

Sandboard or sand-sled

Rent a board in nearby towns; the park doesn't rent them. The dunes make for a genuinely fast, if sandy, ride down.

Wildlife in Great Sand Dunes: Animals You Might See

Tap any animal to learn its story. Soon, the app will let you log what you spot and keep a life list for every park.

Almost never needs to drink free water at all, extracting what it needs from seeds. Its tracks are common on the dunes at dawn, though the animal itself is rarely seen.

Common in the grasslands and forest edges surrounding the dune field, especially active at dawn and dusk.

Works the high, rocky terrain of the mountains ringing the dunes, occasionally visible from the Mosca Pass trail.

A species found only in this dune field and nowhere else on Earth, adapted specifically to life on shifting, sun-baked sand.

Present in the forested slopes bordering the dune field, rarely encountered on the open sand itself.

Hunts the open grasslands and dune edges, occasionally visible riding thermals off the Sangre de Cristo foothills.

Digs extensive burrow systems beneath the dune surface, emerging only at night to forage, leaving distinctive tracks each morning.

Plant Life in Great Sand Dunes: What Grows Here

One of the few plants able to root directly in shifting sand, helping stabilize the dune edges where grassland meets the dune field.

Tracks the seasonal path of Medano Creek, the only reliable sign of where the water flows each spring before it dries up.

A low, silvery-leaved plant found along the dune margins, tough enough to survive the extreme heat of the exposed sand.

Common in the grasslands surrounding the dunes, blooming with bright yellow flowers in late spring.

Covers the lower slopes of the Sangre de Cristo range bordering the park, giving way to alpine tundra higher up.

A low, fragrant flower that appears on the dune margins after summer rains, one of the few blooms tough enough for the shifting sand.
