Great Sand Dunes National Park in Colorado offers a unique, one-of-a-kind outdoor experience. The sand dunes are spread out across 30 square miles, with dunes reaching up to 750 feet high.

The diverse backdrop includes forests, wetlands, lakes, grasslands, and more, so there’s something for everyone to enjoy.

While the park is relatively small and rural compared to other national parks, there are countless exciting activities to explore while in the area. Outdoor enthusiasts will love this park’s extraordinary scenic views and adventures.

You can walk along the sand dunes, sled or sandboard down the dunes, ride horses through trails, hike one of the forested mountain trails, and even camp under the stars.

During the warmer months, visitors can relax and splash around in the shallow Medano Creek or relax on the seasonal beach. The park is open 24/7 year-round, so there’s always something to discover in this scenic destination.

To get the most out of your trip to Great Sand Dunes National Park, should plan plan your visit for the end of spring or the beginning of fall.

Early May is one of the best times to visit the park to enjoy an abundance of activities, avoid crowds, and experience mild, warm weather. Southern Colorado can have extreme wind, cold, and snow during the winter months up through March.

By late April/early May, these blustery conditions are generally over, and you can enjoy high temperatures in the 60s and 70s. The park’s peak season starts around the end of May and goes into the warm summer months.

During this busy season, the park can become crowded with tourists, and it can be difficult to find peace and quiet on the trails or dunes. Visiting in early May, before the crowds roll in, helps ensure that you can enjoy uninterrupted access to all the activities the park has to offer.

The seasonal Medano Creek also flows through the area starting in May, so visitors in the spring can splash around and float in the shallow water to cool off after a day of hiking.

And if you want an unforgettable night under the stars, the park’s campgrounds open in April and don’t get too busy until the summer. While you might miss out on a dip in the creek if you visit in early fall, late September or early November are also great choices when planning your Colorado vacation.

During this time, you can enjoy warm, mild weather and avoid the swarms of tourists that arrive in the peak summer season. The sand dunes can also reach extremely high temperatures during the summer months.

If you’re interested in hiking, exploring, or sledding down the sand dunes, the mild, cooler temperatures in May or September can help you avoid any extreme surface temperatures.

To avoid crowds while exploring Great Sand Dunes National Park, you can visit the area during the quiet winter season between December and February.

The winter months bring snow and below-freezing weather to the sand dunes. During this time, many of the main highlights of the park aren’t as accessible.

There’s limited access to hiking trails, the seasonal beach isn’t available, and the Medano Pass Primitive Road is closed to all traffic.

Because many of the park highlights aren’t available due to weather conditions, not as many tourists flock to the sand dunes when the weather gets cold. Despite the temperatures and closures, however, there’s still plenty to enjoy at the park if you’re trying to avoid crowds.

During the winter, you can participate in snow sports throughout the park, including:

  • Snowshoeing
  • Cross-country skiing
  • Sledding down the dunes

While mountain hiking trails are generally closed, there are also some foothills trails with shallow snow that are still available for hiking.

No matter what time of year you choose to visit Great Sand Dune National Park, you’re guaranteed to find activities to keep you busy and happy.

But with limited activities and freezing weather, January is one of the worst times to visit.

January is the coldest month of the year in Southern Colorado and often brings below-zero temperatures and deep snow throughout the sand dunes. This means that many of the more challenging mountain hikes are closed, and you can’t enjoy full access to all of the park’s activities.

From hiking to horseback riding to swimming, we think that this park is an ideal vacation spot for any adventurous traveler.

But with the beach, trails, scenic roads, and more unavailable in January due to harsh weather conditions, there are significantly fewer things to discover throughout this national park.

Spring, Summer, and Fall bring significantly more activity options, with the seasonal beach, alpine lakes, sand dune hikes, and so much more. But if you want to avoid crowds, you also might want to avoid a trip between June and August.

During these months, the dunes become crowded with families and other visitors. The sand surface can also reach temperatures of 150 degrees during the summer, so be sure to plan around the weather to avoid discomfort and extreme heat during the day.

Despite the middle of Winter and Summer both posing some challenges while planning a visit, it doesn’t mean that there’s nothing to enjoy while there during these times of the year. During the summer, you can enjoy access to all the seasonal activities, especially camping under the starry sky.

And winter sports enthusiasts will find plenty of options throughout the park during the winter months. For a cozy winter visit to the park, you can also stop by the January Rio Frio Ice Festival in the nearby Alamosa.

Now that you know the best and worst times to visit Great Sand Dunes National Park, you’re almost ready to get started planning your trip. But before you book your flight, check out some of the other key things to consider.

These include:

  • Plan for the weather. From blizzards to extreme heat and hot sand, the park sees a wide range of intense weather conditions. Even in the warm summer months, temperatures can quickly drop at night.  When you’re booking your trip, be sure to take a look at the weather forecast so you can be prepared for all the elements while exploring the great outdoors. Bring extra layers, water, sunscreen, and weather-appropriate clothes for any adventure through the park.
  • Book your trip around major holidays. The park is essentially a giant sandbox, making it a perfect vacation for families, particularly with school-aged kids. While this leads to magical and unforgettable family memories, it also means that the park gets extremely busy during holidays. If possible, plan your trip around these school holidays to save money and avoid crowds.
  • Find creative ways to save money. Besides visiting the park during the off-season, there are so many ways you can save money while booking your trip. Throughout the year, you can usually find deals and savings on airline tickets, accommodations, and attractions. Many places also offer student, senior, veterans, or other discounts, so be sure to ask!  You can also set price alerts to find the best deals on flights to Colorado. During the off-season, in particular, it’s simple to find fantastic discounts on flights and accommodation options.
  • Don’t stay confined to just the park. The park offers so many scenic views and exciting activities to explore. But when you’re in the area, be sure to venture outside the park and discover everything else the San Luis Valley has to offer. This beautiful, unspoiled region boasts countless activities to explore, from scenic walks to reptile parks. If you want to escape the summer crowds or escape the snowy winter weather for a day, you can head to Alamosa or other nearby towns and learn all about the area’s rich history.
