Things to Do
Unforgettable experiences await you.
Sandboarding & Sand Sledding
Rent specialized equipment and glide down the massive sand dunes for an exhilarating and unique experience. This activity is fun for all ages and skill levels, offering a thrilling way to engage with the landscape.
Stargazing (International Dark Sky Park)
Experience unparalleled night skies at this designated International Dark Sky Park. On moonless nights, the Milky Way is vividly visible, making it a prime location for astronomy and astrophotography.
Hike Star Dune or High Dune
Challenge yourself by hiking to the summit of Star Dune (750 ft) or High Dune (699 ft) for breathtaking panoramic views of the entire dune field and the surrounding Sangre de Cristo Mountains.
Wade in Medano Creek (Seasonal)
From late April to early June, Medano Creek emerges at the base of the dunes, featuring a unique 'surge flow' phenomenon. This seasonal creek is perfect for wading, splashing, and building sand castles.
The Icons You’ll Want to See
High & Star Dunes — Ascend North America’s tallest dunes, with Star Dune reaching 750 feet. A challenging but rewarding hike (approx. 3-4 miles round trip to High Dune, 2-3 hours) offers panoramic views of the entire dune field and the vast San Luis Valley. Remember to tackle these climbs in the cooler parts of the day.
Medano Creek — Experience a truly unique natural phenomenon at the base of the dunes, typically flowing from late April to early June. This seasonal creek exhibits a mesmerizing “surge flow,” where waves of water appear at regular intervals, creating a natural lazy river perfect for wading, skimboarding, and splashing. Don’t forget your water shoes!
International Dark Sky Park — As a designated International Dark Sky Park, Great Sand Dunes boasts some of the clearest, darkest night skies in the continental U.S. On a moonless night, the Milky Way stretches across the heavens in breathtaking detail, making it an astronomer’s dream. Find a spot away from campground lights, bring a blanket, and prepare to be amazed.
Sandboarding & Sand Sledding — Get your adrenaline pumping by gliding down the sandy slopes. These exhilarating activities require specialized equipment, as regular snow sleds won’t work. Rentals are available from vendors just outside the park entrance (e.g., Oasis Store) or in Alamosa. Plan for early morning or late afternoon sessions when the sand is cooler.
Zapata Falls Recreation Area — Just 11 miles south of the main park entrance, this hidden gem offers a refreshing break from the sand. A short, rocky 0.9-mile round-trip hike leads to a cavern where a partially frozen waterfall is often visible. Be prepared to wade through icy water at the cave entrance (waterproof shoes recommended for the full experience).
Medano Pass Primitive Road — For the adventurous with a high-clearance 4WD vehicle, this 22-mile rugged route traverses a mountain pass, offering stunning views, access to secluded hiking trails, and primitive camping. Check conditions at the Visitor Center before attempting, as it can be challenging.

Travel Tips
Planning Your Visit
A trip to Great Sand Dunes requires a bit of preparation due to its remote location and unique environment. The park is approximately 38 miles northeast of Alamosa, requiring a personal vehicle for access and exploration. The entrance fee is $25 per vehicle for a 7-day pass, or you can use your America the Beautiful National Parks Pass. Remember, the sun is intense at over 8,000 feet elevation, so high-SPF sunscreen, a wide-brimmed hat, and sunglasses are non-negotiable. Carry significantly more water than you think you’ll need (1 liter per person per hour of activity is a good rule of thumb), as there are no potable water sources on the dune field.
Accommodation options include the popular Piñon Flats Campground inside the park (reservations essential, especially in peak seasons), backcountry camping with a free permit, or the nearby Great Sand Dunes Lodge just outside the entrance. More lodging, grocery stores, and dining options can be found in Alamosa, about an hour’s drive away. There are no restaurants within the park, only a small general store near the visitor center for basic snacks, so plan to pack all your food and supplies. Sturdy, closed-toe hiking boots are crucial for the dunes, as sand can reach extreme temperatures in summer, while water shoes are a must for Medano Creek. Be prepared for windy conditions, which can whip up sand, and always practice Leave No Trace principles to preserve this fragile ecosystem.

Sample Itineraries
Dunes & Dark Skies Adventure
Experience the best of Great Sand Dunes: sand sledding, Medano Creek fun, high dune hiking, and unparalleled stargazing in an International Dark Sky Park.
-
Day 1: Dune Discoveries & Creek Cool-Down
- Morning (9:00 AM - 12:00 PM) Arrive at Great Sand Dunes National Park. Your first stop should be the Oasis Store (located just before the park entrance) to rent sandboards or sand sleds. They typically rent for 24-hour periods, costing around $20-$25 per board/sled (Budget: $40-50 for two). Next, pay the park entrance fee ($30 per vehicle, valid for 7 days). Check in at Piñon Flats Campground (reservations are highly recommended and can be made at Recreation.gov; Cost: $20/night). Set up your camp. Afterward, visit the Great Sand Dunes Visitor Center to grab a map, check current conditions, and get tips from rangers. From the Dune Field Parking Area (near the Visitor Center), walk approximately 0.5 miles across the sandy plain to Medano Creek. If it’s flowing (typically late spring/early summer), wade in the water and enjoy the unique “surge flow.”
- Afternoon (12:00 PM - 5:00 PM) Enjoy a packed picnic lunch at one of the picnic areas near the Dune Field or back at your campsite (Cost: Budget-friendly, bring your own food). After lunch, it’s time for the main event: sand sledding! Head into the main Dune Field from the Medano Creek bed. Find a good, moderate slope (many are accessible within a 0.5 to 1-mile walk) and spend the afternoon sliding down the dunes. Be prepared for a workout climbing back up!
- Evening Return to your campsite at Piñon Flats to relax and prepare a simple, budget-friendly campfire dinner (e.g., pre-purchased groceries for foil packet meals, hot dogs, or veggie burgers cooked over the fire). As darkness falls, the true magic begins. Great Sand Dunes is an International Dark Sky Park. Walk from your campground to the Dune Field Parking Lot or find an open spot within the campground for unparalleled stargazing. Lie back and identify constellations, planets, and the Milky Way. Use a red-light flashlight to preserve your night vision.

Day 2: High Dune Ascents & Cosmic Goodbyes
- Morning (6:30 AM - 11:30 AM) Rise early for a packed breakfast at your campsite (e.g., oatmeal, granola bars, fruit). Head back to the Dune Field Parking Lot. Today’s challenge is the strenuous hike up High Dune. This iconic dune offers incredible views but is a challenging climb through soft sand, covering about 1.5 miles one way with a 600-foot elevation gain. Allow 2-3 hours for the round trip. Bring plenty of water and wear appropriate footwear.
- Afternoon (11:30 AM - 4:00 PM) After descending from High Dune, return to camp for a well-deserved packed lunch. If you have any energy left and want a change of scenery, consider a short, easy walk on the Montville Nature Trail (0.5-mile loop) near the Visitor Center, offering shade and a glimpse of the area’s forests. Before heading out of the park, be sure to return your rented sandboards/sleds to the Oasis Store.
- Evening Begin packing up your campsite at Piñon Flats. For a final, budget-friendly meal, you can either have a last picnic at a park table or consider a very simple takeout item from the Zapata Grill at the Oasis Store (e.g., a shared basket of fries). If time and energy allow before you depart, head back to the Dune Field Parking Lot for one last, unobstructed viewing of the incredible night sky, soaking in the silence and vastness of this International Dark Sky Park before your journey home.
Extended Mountain & Dune Exploration
Dive deeper into the park with multi-day dune exploration, a visit to Zapata Falls, and a scenic drive on Medano Pass Primitive Road (4WD recommended).

Head to Pinon Flats Campground ($20/night, reservations highly recommended, book via recreation.gov) and set up your campsite. After settling in, drive to the main Dunes Parking Area. Begin your first dune exploration with a moderate hike towards Montville Dune (approx. 1.5 miles round trip, 1.5-2 hours) to get a feel for sand hiking. Wear closed-toe shoes and bring plenty of water.
- Afternoon (1:00 PM - 5:00 PM) Enjoy a packed lunch at your campsite or a picnic area near the dunes. Head to the Oasis Store (just outside the park entrance) or a rental shop in Alamosa to rent sandboards or sand sleds (approx. $20-25 per board/sled per day). Spend the afternoon sledding or sandboarding on the gentler slopes near the main Medano Creek bed (if flowing) or further into the main dune field. This is a unique and fun way to experience the dunes!
- Evening Prepare a simple, budget-friendly dinner at your campsite (e.g., camp stove meal or pre-made sandwiches). As dusk approaches, take a short walk back into the dunes to witness a spectacular sunset over the vast sandscape with the Sangre de Cristo Mountains in the background.

Day 2: Zapata Falls & Medano Pass Adventure
- Morning (8:00 AM - 12:00 PM) Enjoy breakfast at your campsite. Drive south on Highway 150 for approximately 10 miles to the Zapata Falls Recreation Area. Turn onto the rough 3-mile dirt road (high-clearance 2WD usually fine, but AWD/4WD recommended) leading to the Zapata Falls trailhead. Hike to Zapata Falls (0.9 miles round trip, 1 hour). The final section involves wading through the frigid stream into a narrow rock crevice to see the falls. Wear water shoes or old sneakers! There is no cost for this activity.
- Afternoon (12:00 PM - 5:00 PM) Return to the Great Sand Dunes main entrance area. Pack a lunch to eat on the go. Embark on the Medano Pass Primitive Road. This 22-mile road requires high-clearance 4WD (check park conditions at the Visitor Center before attempting, as it can be seasonally closed). Drive slowly, navigating up to 9 creek crossings (which vary in depth) and enjoying the diverse landscapes from pine forests to open meadows. Drive as far as you feel comfortable, perhaps to the Medano Pass Trailhead (about 11 miles in) or a scenic overlook. Allow 2-4 hours for driving and short stops.
- Evening Return to Pinon Flats Campground. Prepare and enjoy a hearty dinner at your campsite. Share stories and photos from your adventures on Medano Pass and at Zapata Falls. Relax by a campfire (if permitted) and enjoy the tranquility of the mountain and dune environment.
-
Day 3: Deep Dune Trek & Departure
- Morning (8:00 AM - 1:00 PM) Have an early breakfast at camp. For a true “extended exploration,” embark on a challenging and rewarding hike deep into the dune field. Consider a trek towards Star Dune (the tallest dune, approximately 7 miles round trip, 6-8 hours, very strenuous) or just explore the remote areas beyond the initial main dunes, where you’ll find untouched sand waves and solitude. Be sure to carry at least 1 gallon of water per person, snacks, and robust sun protection. This provides incredible panoramic views of the entire dune field and surrounding mountains.
- Afternoon (1:00 PM - 4:00 PM) Return to your campsite for a late packed lunch. Begin to dismantle your camp, ensuring you leave no trace. Before departing the park, make a final stop at the Visitor Center for any last-minute questions, to pick up souvenirs, or just to enjoy the interpretive exhibits one last time. Take in the final breathtaking views of the dunes from the main overlook.
- Evening Begin your drive home from Great Sand Dunes. For a final, budget-friendly meal, consider stopping in Alamosa (approx. 30 miles southwest of the park). Local options like Calvillo’s Mexican Restaurant or a simple diner can provide a satisfying and affordable dinner before continuing your journey. This meal would be part of your overall food budget ($40-50).
