If you think you’ve seen it all—forests, lakes, mountain peaks—wait until you meet the tallest dunes in North America. Great Sand Dunes National Park in Colorado flips the script on what a national park is supposed to look like. Imagine 30 square miles of wave-like dunes set against rugged mountains. Yeah, it’s real—and it’s wild.
This isn't just some Instagram stop. It’s a full-blown landscape of extremes, with sharp contrasts between blazing sand, icy creek flows, alpine trails, and dark-sky brilliance. Whether you’re there for a weekend hit or a slow-burn adventure, this park delivers. And yes, Great Sand Dunes National Park in Colorado is just as epic as it sounds.
The dunes are the stars here—some reaching up to 750 feet high—but the surrounding terrain adds depth. The Sangre de Cristo Mountains form a dramatic backdrop. Medano Creek pulses like a heartbeat in spring. And the park’s dark sky designation means night views that don’t need filters.
This place isn’t a one-trick pony. It’s a sand-forest-alpine hybrid. And that combo? Rare.
The cool part? These dunes were formed over tens of thousands of years from sediments carried by the Rio Grande and its tributaries. The wind then did its thing—piling them up against the mountain range. The result? A surreal, living landscape that constantly reshapes itself. No wonder people come back again and again to see how it changes.
This isn’t a park you drive through. You earn your views here—and the payoff’s worth it. If you're making a list of things to do at Great Sand Dunes National Park, consider this your starting point.
1. Sandboarding and Sledding
Top of the list for a reason. Rent gear from shops in Alamosa or Mosca (because the park doesn’t rent any) and hit the dunes like it’s a desert playground. It’s fun, fast, and slightly chaotic—in the best way. You’ll definitely want waxed boards made specifically for sand—trust the locals on this one.
2. Hike to High Dune or Star Dune
High Dune isn’t the tallest, but it gives the cleanest panoramic shot. Star Dune is a grind, but it’s the king of the park. You’ll feel every step, but the summit silence hits differently. Pack water, start early, and be ready for strong winds at the top.
3. Chill in Medano Creek
In late spring, the creek pulses through the sand in waves. Locals call it “surge flow.” It’s like nature’s lazy river—but short-lived. Best time? Late May to early June. Don’t miss it. Families bring floaties, kids go wild, and dogs love it too.
4. Stargazing
The park is an official International Dark Sky Park. Lay back on warm sand, no light pollution in sight, and just let the Milky Way flex. If you’re into astrophotography, this is your moment. You might catch a meteor shower if your timing’s right.
5. Hike Beyond the Dunes
Trails like Mosca Pass or Medano Lake take you away from sand and into alpine territory. Forests, wildflowers, maybe even a moose sighting if you’re lucky. Mosca Pass gives off total Colorado trail energy with cool views and fewer crowds. Another win for anyone ticking off things to do at Great Sand Dunes National Park.
6. 4WD the Medano Pass Primitive Road
If your ride can handle creek crossings and deep sand, hit this rugged road for real backcountry access. It’s not for regular sedans or the faint-hearted. But the views? Worth every bump. Plus, dispersed camping options are a win.
7. Camp on the Dunes or Nearby
Want next-level solitude? Grab a backcountry permit and camp directly on the sand. Just you, the stars, and the sound of wind. Piñon Flats Campground is great too—clean, well-placed, and close to the action.

Fall: Golden hours stretch longer. Fewer bugs, fewer people. Ideal for hiking and stargazing. Nights are crisp and campfires hit better.
Winter: Below-freezing mornings, snow potential, and bright sun. Dress smart and layer up. If you’re into winter hikes and surreal landscapes, you’ll love it. Keep an eye on the forecast—weather in Great Sand Dunes National Park can shift hour to hour.
