- North America ↗Crossing between the US, Canada and Mexico by land needs your passport even on a day trip; rental cars need the company's written permission to cross, and most US and Canadian rental insurance stops at the Mexican border.
- North America ↗Cannabis is legal in Canada and in many US states, but taking any amount across the US, Canadian or Mexican border is a federal crime — including edibles and vapes.
- North America ↗The busiest US and Canadian national parks need timed-entry, campsite or lodge reservations in summer; release dates are months ahead.
- United States ↗Check whether you need an ESTA (Visa Waiver Program) or a visa on the official CBP and State Department sites; apply only through esta.cbp.dhs.gov, not third-party sites, and allow time before you book.
- United States ↗Several popular national parks use timed-entry or vehicle reservations in peak season; check each park's page on nps.gov and book on recreation.gov before fixing your dates.
- United States ↗Medical care is very expensive for visitors; buy travel insurance with high medical cover before you fly.
- United States ↗Tipping is expected: about 15–20% at sit-down restaurants and bars, and a tip for taxis, hotel staff and guides.

Great Sand Dunes National Park and Preserve protects the tallest dunes in North America — a dune field of roughly 78 km² piled against the Sangre de Cristo Mountains in Colorado's San Luis Valley. The monument dates from 1932; the surrounding preserve was added in 2000 and the whole area became a national park in 2004. There are no marked trails on the sand: you pick a line and climb. In late spring and early summer, snowmelt feeds Medano Creek along the south edge of the dunes, a shallow, sun-warmed stream that draws families wading and picnicking at about 2,500 m. Behind the dunes the park climbs through piñon-juniper and spruce forest to alpine lakes and tundra, with six peaks over 4,000 m. The valley is dry and sunny most of the year, but July and August bring afternoon thunderstorms, and winter brings wind, cold and blowing sand.

About 434 km² (168 sq mi) including the preserve; dune field itself is roughly 78 km² (check).
Why go
- The tallest dunes in North America rise about 230 m against the Sangre de Cristo Mountains — a walkable, climbable landscape with no marked trails.
- Medano Creek runs along the south edge of the dunes in late spring, creating a shallow beach at 2,500 m altitude.
- The park protects a full elevation range, from dune field to alpine tundra and six peaks over 4,000 m.
- Dark skies: the San Luis Valley has little light pollution, so the dune field is good for stargazing.

Time out
Finding the local time zone…
Times are local to the spot (zone loading). The half-hour margin is our rule of thumb, not an official figure; light fades earlier in forest or under cloud. Carry a headlamp on any route that could run late.
Accessibility
- The visitor center, picnic area and a paved viewpoint are accessible by car with short walks.
- The dunes themselves are loose sand; wheelchairs with wide tyres can reach the lower slopes but not the summits.
- Piñon Flats Campground has some accessible sites; check when booking.
Visiting lightly
- Stay on durable sand and avoid the vegetated edges, where trampling damages stabilising plants.
- Do not remove sand, plants or artefacts.
- Pack out everything, including food scraps that attract wildlife.
- Visit in May, June, September or October to spread pressure away from the July–August peak.
Questions people ask
How much does it cost to enter Great Sand Dunes National Park?
In 2026 the entrance fee is about $25 per private vehicle, $20 per motorcycle or $15 per person arriving on foot or bike, valid for 7 days (check current rates). The America the Beautiful annual pass, about $80, covers this park and most other federal fee areas for 12 months.
What are the best hikes in Great Sand Dunes National Park?
High Dune is the standard first climb: 2–3 hours round trip over loose sand with about 200 m of gain. Star Dune is the tallest in North America and takes 4–5 hours. For firmer ground, the Mosca Pass Trail is about 11 km round trip through forest, and the Medano Lake route climbs into the high country.
When is the best time to visit Great Sand Dunes National Park?
Late May to June for Medano Creek and mild days, or September to October for cooler, clearer weather and fewer people. July and August bring afternoon thunderstorms and hot sand; winter is cold and windy, with blowing sand and possible road closures.
Do I need a permit to camp in the dunes?
Yes. Overnight stays in the dune field and the high country need a free backcountry permit from the visitor center. Piñon Flats Campground is the only developed campground and needs a reservation or a first-come site.
Can I sandboard or sled down the dunes?
Yes, sandboarding and sledding are allowed on the dunes. There are no rentals inside the park, so bring or rent a board in Alamosa or at the entrance-area shops; waxed boards slide better than plastic sleds on dry sand.
Is there anywhere to stay inside the park?
Only Piñon Flats Campground, plus backcountry camping with a permit. Otherwise stay just outside the entrance on CO 150, or in Alamosa about 50 km southwest, which has the widest choice of motels.
How do I get to Great Sand Dunes without a car?
It is difficult. There is no public transport to the park; the nearest airport with connections is Alamosa, and from there you still need a car or a taxi. Most visitors drive from Denver, Colorado Springs or Santa Fe.
