Beneath Shifting Ridges: Hiking and Camping the Great Sand Dunes
Climb sand, camp under an alpine sky—how to experience North America’s tallest dunes with intention and ease
A wind-scrubbed plain yawns beneath a high alpine skyline: the Sangre de Cristo Range looms like a wall, its serrated profile a constant horizon as you climb a slope of sand that sighs underfoot. Each step sinks a little, wind combing your path into new ridges; behind you the valley glitters with the improbable green of irrigated fields and the narrow ribbon of Medano Creek that dares you to follow it. At the crest, the desert opens—an ocean of rippled dunes that fall away to the Sangre de Cristos’ alpine shadow. It’s a landscape that misleads the eye and humbles the body: the tallest dunes in North America sit not on a seaside coast but in the heart of southern Colorado.
Trail Wisdom
Start early or go late
Temperatures drop and sand firms up outside midday—plan your main climbs for sunrise or late afternoon to avoid heat and deep-sink sand.
Carry ample water
In summer, aim for at least 1 liter per hour of exertion—there’s no reliable shade or water on the dunes themselves.
Protect gear from sand
Use dry bags or zip-locks for electronics and keep a small brush or sock to clear sand from zippers and tent seams.
Watch the weather
Mountain storms can produce strong winds and lightning quickly—head to lower ground and avoid exposed ridge-lines if storms approach.

Conservation Note
The park balances recreation with sensitive dune and aquatic habitats—stay on established routes, avoid disturbing vegetation anchoring the dunes, and pack out all waste.
The dunes formed over thousands of years from sand eroded off the Sangre de Cristo Range and trapped by seasonal winds in the San Luis Valley; the area later gained protection as a national park in 2004 after long conservation efforts.
Seasonal Guide
spring
Best for: Medano Creek play, wildflower viewing, moderate hikes
Challenges: variable creek flow, cool nights, muddy access after snowmelt
Spring brings Medano Creek to life—bring sandals for creek play and layers for cool nighttime temperatures.
summer
Best for: night sky viewing, long daylight hours, family sand play
Challenges: extreme daytime heat, afternoon thunderstorms, very soft sand
Summer is peak visitor season—avoid midday heat, expect brief mountain storms, and schedule hikes for cooler hours.
fall
Best for: comfortable hiking temps, photography, fewer crowds
Challenges: windy days, shortening daylight, colder nights
Fall offers ideal hiking weather and vivid light; bring warm layers for crisp mornings and cold nights.
winter
Best for: wind-sculpted landscapes, solitude, unique photo opportunities
Challenges: cold temperatures, potential road closures, very stiff sand surfaces
Winter creates stark, sculpted dunes and empty trails—dress for cold and check road conditions before you go.
Photographer's Notes
What to Bring
2–3 liters hydration systemEssential
Keeps you hydrated during strenuous dune ascents when no water sources exist.
Low-profile tent with solid stakesEssential
Holds up in wind and keeps sand out during overnight stays on the dune edge.
Sun protection (wide-brim hat, sunscreen, UV sunglasses)Essential
Reflective sand increases UV exposure—protect skin and eyes.
Plastic sled or plywood runner
For downhill fun—simpler sleds perform better on dry, compacted sand.
Common Questions
When does Medano Creek flow reliably?
Medano Creek typically flows in spring and early summer after snowmelt; flow can vary widely by year depending on mountain snowpack.
Are there fees to enter the park?
Yes—Great Sand Dunes National Park charges an entrance fee per vehicle; annual and interagency passes are accepted.
Can I drive onto the dunes?
No—vehicle access onto the dunes themselves is prohibited to protect fragile habitats; use designated roads and parking areas.
Is sand sledding allowed year-round?
Sledding is permitted on the dunes but conditions depend on sand firmness; spring/early summer and fall often offer the best runs.
Are dogs allowed?
Dogs are allowed in developed areas and on roads but are restricted on most trails and are not recommended on exposed dunes during hot weather.
Is camping available on the dunes?
Camping is allowed in designated backcountry dune areas and in the developed Piñon Flats Campground; backcountry campers must follow Leave No Trace and park regulations.
What to Pack
Sturdy hiking shoes (sand grips and ankle support), sun protection (hat, sunglasses, SPF), 2–3 liters of water (hydration needs), windproof shelter (low-profile tent or tarp)
Did You Know
Great Sand Dunes contain the tallest sand dunes in North America, with some dune faces rising over 750 feet above the valley floor.
Quick Travel Tips
1) Fill up on fuel and water in Alamosa before heading to the park. 2) Check the park website for current Medano Creek flow and road conditions. 3) Bring a change of clothes and sealable bags to stash wet sand. 4) Time your hike for early morning or late afternoon to avoid heat and soft sand.
Local Flavor
Dinner in Alamosa pairs hearty New Mexican-influenced fare—think green chile, grilled bison, and craft beers—while local outfitters offer guided dune tours, sled rentals, and interpretive walks in season.
Logistics Snapshot
Drive time: ~2.5 hours from Colorado Springs; Nearest services: Alamosa (20–30 minutes). Park fees apply. Cell reception is limited—download maps and notify someone of backcountry plans.
Sustainability Note
Stick to designated roads and campsites, avoid creating new trails on dune vegetation, and carry out all trash; small actions help preserve the dunes’ fragile ecosystems and medano creek habitat.
