The Best Time to Visit Great Sand Dunes National Park in 2024

What's the best time to visit Great Sand Dunes National Park?

The best times to visit Great Sand Dunes National Park are in early May and late September to early November, avoiding peak crowds and enjoying mild weather. Early May allows for activities like floating in Medano Creek, while both periods offer ideal conditions for hiking and exploring with cooler sand temperatures. These times also provide opportunities for quieter camping and stargazing.

A trip to Great Sand Dunes National Park, nestled by the Sangre de Cristo Mountains in Southern Colorado, is guaranteed to provide incredible views, hours of fun, and unforgettable memories for every visitor.

But if you’re planning a trip to these tallest sand dunes in North America, it’s crucial to make the most out of your time in the park. Knowing the best time of year to visit can ensure that you have the best possible experience exploring this destination.

Whether you’re looking for warm weather and an abundance of activities, want to avoid crowds, or are searching for the cheapest airfare, there’s a time to visit the park that can meet your needs.

The overall best time to visit Great Sand Dunes National Park is at 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.

The cheapest time to visit Great Sand Dunes National Park is in the cold winter season between December and March. With fewer tourists visiting the park during these colder months, visitors can save money on the lodges and cabins near the entrance of the park.

Many of these accommodation options have seasonal pricing, so you can save money while exploring the park by visiting during the off-season.

When it comes to booking your flight, planning a trip for the winter offers cheaper flight options compared to the busier summer seasons. January specifically is one of the cheapest times of year to fly to Colorado, so be sure to take advantage of the low prices when planning your trip.

The least busy time to visit Great Sand Dunes National Park is 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.

And best of all, you can explore the park and discover all this incredible destination has to offer while enjoying the peace, quiet, and solitude of this rugged and rural park.

The worst time to visit Great Sand Dunes National Park is in January, when the park has limited activities and freezing weather.

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.
