In this complete guide, we’ll explore everything you need to know about Great Sand Dunes National Park, including its unique landscape, best things to do, when to visit, and travel tips. Whether you’re planning a family vacation or a solo trip, this guide has you covered.

What Makes Great Sand Dunes National Park Special?

Great Sand Dunes National Park and Preserve is located near Alamosa in southern Colorado. What makes it truly unique is the contrast between its towering sand dunes and the surrounding alpine wilderness.

Here are some fast facts:

Dune height: Up to 750 feet tall — the tallest in North America
Area covered: Over 149,000 acres
Established: Became a national park in 2004
Ecosystems: Includes grasslands, wetlands, alpine lakes, forests, and tundra

What sets this park apart is that it’s not just a desert — it’s a combination of sand, water, mountains, and sky.

A Brief History of the Sand Dunes

The dunes began forming over 400,000 years ago, as sand and soil from the surrounding mountains were carried by wind and water. Over time, wind trapped the sand at the base of the Sangre de Cristo Mountains. The result? A massive dune field that looks like something straight out of a desert movie scene.

Before it became a national park, the area was home to Native American tribes, Spanish explorers, and early settlers. Many Native Americans considered the dunes sacred, and today, the park works closely with tribal leaders to preserve cultural sites.

Top Things to Do in Great Sand Dunes National Park

1. Sandboarding and Sandsledding

This is the most popular activity in the park. Visitors can rent special boards or sleds from nearby shops in Alamosa or Blanca. Then, climb the dunes and ride down like you’re surfing a sandy wave. Medano Creek at the base of the dunes is a great starting point.

Tip: Regular snow sleds won’t work. Use specially designed sand sleds or boards.

2. Hiking the Dunes

If you’re up for a physical challenge, hiking to the top of Star Dune or High Dune on First Ridge will reward you with breathtaking views. There are no marked trails on the dunes, so you can roam freely.

Star Dune: Highest dune, 750 feet tall
High Dune: Slightly easier and offers panoramic views

3. Medano Creek Fun

In late spring and early summer (May to early June), Medano Creek flows strongly, creating a natural beach at the foot of the dunes. It’s perfect for splashing, building sandcastles, and cooling off.

4. Stargazing

Because of its remote location and low light pollution, Great Sand Dunes National Park is a designated International Dark Sky Park. On clear nights, the sky lights up with stars, and you can often see the Milky Way.

5. 4WD Off-Roading

If you have a 4WD vehicle, you can explore the Medano Pass Primitive Road, which leads into the Sangre de Cristo Mountains. It’s a rugged, scenic route, especially beautiful in the fall.

6. Hiking and Backpacking

Beyond the dunes, the park offers forest trails, waterfalls, and alpine lakes. Popular hikes include:

Mosca Pass Trail – A 6-mile round trip through forests and meadows
Zapata Falls – A short hike outside the park that leads to a hidden waterfall
Sand Ramp Trail – A longer backpacking route along the dunes’ eastern edge
