Epic Guide to Great Sand Dunes National Park and Preserve in Colorado

Below you’ll find the ultimate guide to Great Sand Dunes National Park, including things to do, how to get there, the best times to visit, where to camp, and more.

Great Sand Dunes National Park

Great Sand Dunes National Park and Preserve protects the tallest dunes in North America.

The park is located at the foot of the Sangre De Cristo Mountains in Colorado.

Star Dune is an epic 775 feet tall. Visitors have the opportunity to explore 30 square miles of sand dune field.

Did you know that Bing Crosby even wrote a love song about the park? His 1940 hit "The Singing Sands of Alamosa" is based on the sounds he heard within the park.

The park features not only a giant sand dune field but also alpine lakes and tundra at the highest elevation of the park.

Lower in the park are grasslands and shrublands that feature vast stretches of grass and wildflowers.

One of the really great things about visiting the park is every time you visit it will have changed. The sands shift with the wind, Medano Creek appears and then settles into dust and the weather shifts during the year.

Colorado’s Great Sand Dunes National Park is at once intensely picturesque and fabulously fun place. Evolved over centuries by unique wind patterns on the San Luis Valley floor, eons of sifting and building, created epic dunes almost 800 feet tall and spanning for miles.

The park’s biology and geology create awe-inspiring and one-of-a-kind conditions rivaling more traditional parks. There are a large array of habitats to explore, from aspens and pines to sand dunes, shrub and grasslands, and even tundra and thick spruce-fir forests.

About Great Sand Dunes National Park

As the name suggests, Great Sand Dunes National Park is home to some pretty spectacular sand dunes.

In fact, the park boasts the tallest sand dune in all of North America, with the highest peak reaching over 750 feet! This mega 30 square mile sandbox is one of the country’s coolest outdoor playgrounds, and visitors flock to southern Colorado to sandboard and sled down the epic slopes.

Believe it or not, there’s so much more to this park than its sizeable sand dunes.

Its location between the Sangre de Cristo mountain range and the San Luis Valley means that there is a wide variety of terrain to be explored.

So, you can glide down dunes, explore alpine lakes, and watch hoards of elk and pronghorns grazing grasslands all within the same park.

There are also several hiking trails and some pretty fantastic stargazing opportunities here as well.

The park has the highest sand dunes in North America, that rise to a maximum height of 755 feet, from the floor of the San Luis Valley.

This group of dunes covers about 19,000 acres and according to the researchers, began to form 440,000 years ago.

The park also has mountain lakes and high mountain tundra, six peaks above 12,795 feet tall, old spruce and pine forests, meadows, and wetlands, etc.

All these environments are home to various species of animals and plants.

An extraordinary phenomenon can be observed on Medano Creek, a creek east of the dunes near the visitor center.

Because fresh sand trickles evenly into the water, the stream does not find a stable and permanent river bed. This creates small underwater dunes that form dams and collapse again.

To get to the dunes you have to cross the wide and very shallow Médano Creek, which runs only from spring until the beginning of summer. Hiking is permitted, with the announcement that the sand can be very hot in the summer, up to 60 degrees Celsius.

Is Great Sand Dunes National Park worth visiting?

While it is quite a ways off the beaten path, Great Sand Dunes National Park is absolutely worth visiting. The scenery is spectacular, and there are tons of fun activities to keep you entertained for hours (or even days) on end.

Certain times of year are better for visiting the park than others, so keep reading to find out everything you need to know for planning your trip.

History of Great Sand Dunes National Park

Human history at Great Sand Dunes National Park dates back about 11,000 years, and there is even evidence of nomadic tribes hunting mammoths through this area.

The Navajo and Ute tribes once called this place home, and the nearby Bianca Peak is considered one of the four sacred peaks to the Navajo Nation.

The dunes are created by the sand and sediment deposits of the Rio Grande and its tributaries, that flow through the San Luis Valley.

With the passing of the years, winds from the west collect the sand particles from the lands flooded by the river and when the wind loses its strength, before crossing the Sangre de Cristo Mountains, it deposits the sand at the eastern end of the valley.

This process continues and the dunes grow slowly as the wind molds them again and again, each day.

The dunes are pretty much stable but with the passing of season after season, their morphology changes a bit, their shape being affected by the wind intensity and direction.

The wind normally goes from the SW to the NE but at the end of summer, the wind turns around creating the dunes. This is why the dunes are so high!

Best time to visit Great Sand Dunes National Park

The best times to visit Great Sand Dunes National Park include spring, early summer, and autumn. This is when conditions are best for enjoying all aspects of the park.

For obvious reasons, these are also the busiest times at the park, so try to arrive early in the mornings and avoid weekends and holidays if you want to evade the crowds.

Weather and Seasons

Spring

Early spring is one of the worst times to visit, specifically the months of March and April. This is when the winds are at their highest, and the snow is at its deepest levels.

These conditions make most of the park inaccessible, including the dunes and most of the trails.

Late spring brings near-perfect conditions to the park, but it also brings plenty of crowds along with it.

May is especially busy, but the snow is mostly gone and the temperatures are still bearable. This is also the month to visit if you’re hoping to see Medano Creek is at its fullest.

The weather can be sporadic year-round, so be prepared for high winds in the afternoon.

Summer

Early summer is another great time to visit the park, specifically the month of June.

Just like May, June sees some of the highest visitation rates of the year, mostly due to great weather and the fact that the Medano Creek is still flowing.

July and August are bearable if you visit during the morning hours, but keep in mind that while the air temperature may seem moderate, the sand can reach scorching heights of up to 150 degrees Fahrenheit by mid-afternoon.

Mid-day thunderstorms are also not unheard of in the summer months. Even in the summer, nighttime temperatures often dip down to the mid-40s. The perk of visiting in July and August? Colorful wildflowers in full bloom.

Autumn/Fall

The autumn may be the best time to visit the park if you are hoping to avoid the crowds. Temperatures are also mild during these months, and the fall foliage is at its peak.

While the Medano Creek is often dried up by this time, it’s not usually warm enough that visitors need it to cool down during these months.

Winter

Unless you are passing through the area and want to check out the Visitor Center, visiting Great Sand Dunes National Park is not recommended during the winter.

While the park is open year-round, heavy snowfall usually makes accessing the dunes and hiking trails impossible. The cold temperatures are also not ideal during these months.

Best Things to do in Great Sand Dunes National Park

Wildlife viewing

While a sandy desert may not seem like a desirable habitat for many animals, the park’s forests and grasslands are the perfect settings for a wide variety of wildlife.

At sunrise, you can see pronghorns grazing, and if you’re awake around dawn or dusk, you might spot one of the nine species of owls that call the park home.

Other critters you might catch sight of include bears, bighorn sheep, bobcats, elk, kangaroo rats, and tiger salamanders.

Junior Ranger Program

The Junior Ranger Program is a great way for the youngsters in your group to learn more about the park in a fun, hands-on way. Once they complete the program, they’ll even receive a cool badge to commemorate their trip.

Sand Boarding & Sledding

No trip to Great Sand Dunes National Park would be complete without trying your hand at sandboarding.

This is by far the most popular activity in the park, and this epic pastime is one of the best ways to get a feel for just how spectacular the dunes really are.

Depending on how high you climb, you’ll also get some fantastic views of the park from up top the dunes.

You can climb up as high as you want to on the dunes and then glide down the sand.

Keep in mind that this is no easy feat, and one step forward often feels like two steps back in the heavy sand.

Some of the highest dunes take up to six hours for experienced hikers to tackle, so plan accordingly and stay hydrated!

The high altitude can also make reaching tall heights extremely difficult for some visitors.

Hot sand temperatures and high winds also present a challenge, so wear proper foot coverings and bring a bandana or some other type of mouth guard along if you want to sandboard or sled.

Board and sled rentals are unavailable inside the park, so you’ll need to stop at a private outfitter before entering the park.

Rentals are available seasonally at the Oasis Store, located just outside of the park, and at other outfitters in Alamosa and Blanca.

Dark Sky Park

Due to its remote location far from city lights, the dry air, and its high elevation, Great Sand Dunes National Park is a great place for stargazing.

The park is recognized as an International Dark Sky Park, allowing nighttime visitors incredible views of the night sky.

The park was recognized in 2019 as a certified International Dark Sky Park by the International Dark Sky Association.

The Milky Way is most visible on nights without a moon from mid-summer through early fall evening.

Medano Pass Primitive Road

4WD vehicles are required for Medano Pass Primitive Road!

All-Wheel-Drive (AWD) vehicles, mini-SUVs, wagons, and similar vehicles with lower clearance will get stuck in the deep sand or creek crossings.

ATVs and UTVs are not permitted within the park. All vehicles used in the park must be highway legal in Colorado.

Medano Pass Primitive Road is a 22-mile road that connects Great Sand Dunes NP and Preserve with the Wet Mountain Valley and Colorado State Highway 69.

It is only open/passable in the summer warm months and with high clearance 4wd vehicles.

The road passes Medano Pass which has an elevation of 10,040 feet. Along the route, you will cross areas of deep sand along with crossing Medano Creek 9 times.

How to beat the crowds in Great Sand Dunes National Park?
