Camping World’s Guide to RVing Great Sand Dunes National Park and Preserve

When most people think of Colorado, they think about the Rocky Mountains and popular ski towns. The Great Sand Dunes National Park and Preserve can often be overlooked, but it is one of the state’s most notable spots!

The sand dunes, which are believed to have started forming about 440,000 years ago from the combination of opposing winds and a huge supply of sand from the valley floor, are the tallest in North America. They’re a must-see for any RVer.

Why Visit Great Sand Dunes National Park and Preserve in an RV?

Great Sand Dunes National Park

Not only are the sand dunes a rare natural phenomenon, but the entire area surrounding the national park is filled with beauty. As you drive to the park, you’ll quickly fall in love with the San Luis Valley and be greeted with sweeping views of the Sangre de Cristo Mountains on the east and the San Juan Mountains to the west.

Once inside the park, you’ll be amazed by its diversity. Its high desert landscape is home to lakes, forests, wetlands, grasslands, meadows, and shrublands. Plus, with over 100,000 acres to explore, you’re sure to find what excites you most!

Great Sand Dunes National Park and Preserve was also recently named one of the quietest national parks, which is just another feature that makes it feel somewhat bizarre. It’s truly a park of contrasts that you have to see to believe.

You can enjoy a visit to the park any time of the year, although summer can be very hot and crowded.

Great Sand Dunes National Park in the Spring

Spring will give you the most comfortable temperatures. However, it can be really windy, and March and April are the snowiest months.

Great Sand Dunes National Park in the Summer

The sand surface temperatures have reached up to 150°F in the hottest months of the year! Summertime also brings many thunderstorms to the area, so it’s best to enjoy the park early in the morning or during the evening.

Great Sand Dunes National Park in the Fall

Early fall tends to be the best time to visit the park, with mild temperatures.

Great Sand Dunes National Park in the Winter

Don’t let the winter weather deter you. The area is generally sunny throughout winter, and because of its dry air, it doesn’t feel as cold as more humid destinations. Remember that most of the programs offered take place from May through September.

How to Get Around Great Sand Dunes National Park and Preserve

The most common route to the Great Sand Dunes is to take I-25 to Walsenburg, west on US 160, then north on State Highway 150. Once you turn onto CO-150, you can follow it right into the park.

If you’re coming from within Alamosa, you can take CO-7 north to County Lane 6 and go east until you get to CO-150. It’s best to follow the map on the NPS website, as GPS units have been known to lead visitors to primitive 4WD-only roads.

Once inside the park, you’ll want to be aware of areas requiring a high clearance vehicle and check road conditions before heading out to explore.

Places to Go

If it’s your first visit to Great Sand Dunes, here are the must-see spots:

The Dunes


There are no designated trails in the 30-square-mile dune field, and hiking up the dunes is quite challenging. In fact, it takes the average person about an hour to reach the top of the first dune ridge. If you’re up to the challenge, the high dune on the first ridge is the most popular destination and provides a great view of the entire dune field.

The more advanced explorers who are willing to spend about five hours round trip can enjoy Star Dune, the tallest dune in North America (750 feet). Lastly, if you have a high clearance 4WD, you can drive right to Eastern Dune Ridge to enjoy views of its impressively tall, steep dune face. Otherwise, 2WD vehicles must drive part of the way and hike 3/4 mile to reach it.

Medano Creek

Medano Creek is at the base of the dunes and easily accessed from the parking lot. It offers a beach-like environment at Great Sand Dunes, and visitors love splashing in the shallow waters. When creek flow is high, you might even spot some children floating on rafts in the waters.

During certain conditions, a phenomenon called “surge flow” occurs where sand forms and falls in the creek bed, creating waves that look like the ocean. You can check the Medano Creek conditions here.

Medano Pass 4WD Road

medano-pass-rving-great-sand-dunes-national-park-09-2022Photo by marekuliasz via Shutterstock

This is not your average road! Medano Pass is 22 miles of sandy, rocky, and wet terrain that is only passable with a high-clearance 4-wheel drive vehicle during warmer months. It will take you about 3 hours to drive the entire road, which connects Great Sand Dunes with the Wet Mountain Valley and Colorado State Highway 69 and gives access to Great Sand Dunes National Preserve.

You’ll want to check the road conditions ahead of time and follow the NPS’s recommendations for reducing your tire pressure and follow their mileage chart to ensure your safety.

Other Nearby Attractions

There’s so much to see and do outside the park too! Take a hike to Zapata Falls and along other trails inside the Rio Grande National Forest and the San Isabel National Forest that both surround the park.

The San Luis Valley is also home to three national wildlife refuges, perfect for bird watching. The nearby towns of Alamosa and Mosca are filled with history and eclectic culture, and Hooper is home to the UFO Watchtower if you’re into paranormal activity!

Things to Do in Great Sand Dunes National Park and Preserve

There’s plenty to do in the park, and each activity will help you learn to love this area even more. Here are some of the top activities.

Sandboarding and Sledding

Colorado is known for its skiing, and the park offers its own version. You’ll find that the first activity most visitors want to enjoy is hiking to the top of the dunes, only to slide right back down on a sled or sandboard

Sandboarding and sand sledding are permitted anywhere on the dunes, so long as you stay away from vegetation, but you’ll be greatly disappointed if you bring just a standard sled or board. You’ll need one with an extra slick base material and possibly even special wax for it to work in the sand. The NPS does not rent gear, but there are several nearby retailers that do.

In addition to the dunes, there are plenty of hiking trails in the park for exploring its alpine lakes and tundra. Here are a few forested trails to help you escape direct sunlight during your visit.

Montville Nature Trail: A short hike with views of the dune, valley, and Mt. Herard. Mosca Pass Trail: About 3.5 miles one way along a small creek to a low mountain pass. Medano Lake Trailhead: Begins at 10,000 feet and leads to an alpine lake. Experienced hikers can continue along the trail to the summit of Mt. Herard at 13,297 feet above sea level. Music Pass and Sand Creek Lakes: A 2.5-hour drive from the visitor center and an 8-mile round-trip hike to the lakes. But it’s worth it for some of the most beautiful alpine scenery in the area. Sand Sheet Loop Trail:  An easy interpretive trail at the visitor center with glimpses of the grasslands.

The grasslands, wetlands, and shrublands in the park are also great for exploring, but access is limited, and a guided tour, or at least a good map and a ranger’s advice, is recommended.



Great Sand Dunes National Park was recently recognized as an International Dark Sky Park. With its dry air, high elevation, and lack of light pollution, it’s an ideal destination for night sky viewing.

Plan your visit during a full moon and enjoy a late-night hike along the dunes with no need for a flashlight! Or, bring your telescope and camera to capture the milky way. The park also offers night programs to learn about and experience the night sky and nocturnal wildlife in the area.
