This comprehensive guide provides everything you need to plan your perfect trip to the Great Sand Dunes National Park and Preserve. We’ll delve into the park’s captivating history and culture, highlight must-see points of interest, recommend the best hiking trails, and explore other popular activities. We’ll also cover practical information such as camping options, lodging, dining, directions, park fees, and accessibility.
History and Culture
The majestic dunefield, the park’s centerpiece, represents approximately 11 percent of an immense sand deposit stretching across more than 330 square miles within the San Luis Valley. Long before the arrival of modern-day visitors, the towering dunes and the imposing peaks of the Sangre de Cristo Mountains served as vital hunting and gathering grounds for various Native American tribes. These included the Ute and Jicarilla Apache peoples. Early explorers, intrepid gold miners, determined homesteaders, hardworking ranchers, and resourceful farmers also relied on these natural landmarks for navigation and sustenance. Archaeological evidence indicates human presence in the area dating back an astounding 11,000 years.
Certain locations within the Great Sand Dunes National Park and Preserve hold profound spiritual significance. Blanca Peak, situated southeast of the dunes, stands as one of the four sacred mountains revered by the Navajo Nation (Diné). Known as Sisnaajini ("white shell mountain"), it is believed that the deities crafted this mountain from a shell and a bolt of lightning as the Diné people entered the "glittering world" for the first time, emerging through a massive reed. The Tewa/Tiwa-speaking pueblos along the Rio Grande believe that the lake from which their people emerged into the present world resides within the San Luis Valley. This sacred site, Sip’ophe ("sandy place lake"), is thought to be a spring and/or lake situated immediately west of the dunefield.
Things to Do
Your exploration of the Great Sand Dunes should commence at the visitor center. Open daily year-round, except for federal winter holidays, the center offers a wealth of information, including engaging exhibits, an informative film, passport stamps, restrooms, and a well-stocked park store. It’s also the place to acquire backcountry permits for overnight adventures.
The next item on your agenda is, of course, conquering the dunes themselves! Unlike many parks, the 30-square-mile dunefield has no designated trails, inviting you to forge your own path through the undulating landscape. The High Dune on the first ridge is a popular destination, offering panoramic views of the entire dunefield. For those seeking a greater challenge, Hidden Dune and Star Dune are tied as the tallest dunes in the park and in North America, both reaching a height of 741 feet. A round trip hike to either of these behemoths typically takes about six hours. During the summer months, the sand surface temperature can soar to a scorching 150 degrees Fahrenheit from late morning through late afternoon. Therefore, it’s advisable to hike in the early morning or evening to avoid the extreme heat.
Sandboarding and sledding are popular activities on the dunes. Keep in mind that specialized equipment is necessary, as cardboard and snow sleds are ineffective on dry sand. If you don’t have your own equipment, you can rent it from outfitters located outside the park, such as Oasis Store, Kristi Mountain Sports (in Alamosa), and Spin Drift Sand Board Rentals (in Blanca).
Medano Creek, flowing along the base of the dunes, offers a refreshing respite from the heat. However, the creek’s flow is seasonal, typically starting in April and peaking in May and June. These are the best months to witness the unique surge flow phenomenon, where waves are created by sand collapsing into the creek bed. The creek usually dries up by July and is completely gone by August.
Beyond the dunes, the park and preserve boast a wealth of natural wonders, including the majestic Sangre de Cristo Mountains (often snow-covered in winter), picturesque piñon pine groves, grasslands where elk frequently graze, vibrant wildflower patches in spring, dense forests, serene wetlands, and winding streams. Many of these ecosystems and landmarks can be explored on foot. For a scenic driving experience, consider four-wheeling along the Medano Pass Primitive Road, especially in late September and October when the autumnal colors are at their peak.
Throughout the summer and fall, the park offers ranger-led activities and evening events. The schedule is posted at the visitor center and the campground. A junior ranger program provides children with the opportunity to earn a badge or patch upon completion of engaging activities. Due to its high elevation, dry air, and remote location, the park is an exceptional destination for stargazing.
Best Hikes and Trails
The Great Sand Dunes National Park and Preserve offers a variety of trails to suit hikers of all skill levels. Before embarking on a hike, confirm whether or not a 4WD vehicle is required to access the trailhead. Snow may block alpine trails from November to June.
As mentioned earlier, the dunes themselves offer unparalleled hiking opportunities. High Dune typically requires a two- to three-hour trek. Reaching the summit involves a climb of approximately 693 feet over 2.5 miles. Hidden Dune and Star Dune each require about six hours of hiking from the Dunes Parking Lot. Eastern Dune Ridge presents a tall, steep dune face accessible from the Sand Pit or Castle Creek picnic areas. Accessing these picnic areas requires a 4WD vehicle. Alternatively, you can park at the Point of No Return and hike either 0.75 miles or 1.5 miles to the picnic areas, both of which offer access to Medano Creek. Consider hiking here under the enchanting glow of a full moon.
Where to Camp
The Great Sand Dunes offers several camping options within its borders. Piñon Flats Campground, open from April through October and located one mile from the visitor center, is the main campground. It features 91 sites, including three group areas. The RV and tent sites offer tent pads, fire pits, food lockers, utility sinks, grills, dump stations, picnic tables, flush toilets, and quiet areas. Showers are not available at this facility. At least one adult must stay at each campsite.
Reservations for Piñon Flats Campground must be made through recreation.gov and cost $20 per night. Reservations can be made up to six months in advance for individual sites and one year in advance for group sites. Early reservations are highly recommended, especially during peak season, weekends, and holidays.
Backcountry camping offers a more adventurous experience. The park offers two backpacking options: seven designated sites along the Sand Ramp Trail and 20 undesignated sites in the Dunes backcountry. Backpacking is permitted year-round, but be prepared for snow and frigid temperatures in winter and high winds and lightning storms in spring and summer. Backpackers must purchase permits online for $6. Permits are available on a rolling basis three months prior to the trip start date. Only gas stoves are permitted, water must be brought in, and all trash, including toilet paper, must be packed out. Scented items should be bagged and hung from trees due to the presence of bears in the area.
The Medano Pass Primitive Road in the preserve section features 21 numbered camping spots. These sites begin 5.2 miles from the road’s starting point. A high-clearance 4WD vehicle is required to navigate the deep sand and creeks along this road. These sites are free and available on a first-come, first-served basis. The road typically closes in winter, from late November to mid-May. The sites and road can also be accessed by fat-tire bikes.
Where to Stay
If you prefer lodging over camping, several options are available near the main entrance. Great Sand Dunes Lodge is a motel offering stunning mountain views. Great Sand Dunes Oasis offers a small lodge and rustic cabins. The Rustic Rook Resort features canvas glamping tents. Larger motels and chain hotels can be found in nearby communities such as Hooper and Alamosa.
Where to Eat
Picnicking is the only dining option inside the park. The picnic area is located along the edge of the dunes and the seasonal Medano Creek. Each site includes a table and charcoal grill, with most offering shade. A restroom is available during the summer months. Two sites are designated for large groups: North Ramada (first-come, first-served) and South Ramada (reservations required).
The Oasis Restaurant and Store is the closest full-service eatery, located at the main park entrance. It is open from April through October and offers groceries and gas in addition to meals. A wider variety of restaurants can be found in Alamosa.
How to Get There
The park is located in a relatively remote area. The closest airport is Alamosa’s San Luis Valley Regional Airport, serviced by United Airlines and located 31 minutes from the park. Denver and Albuquerque are each approximately four hours away by car.
