Events & What’s Happening
Each spring, snowmelt creates a seasonal beach-like creek at the base of the dunes, forming wave surges that families can wade through in a unique desert water experience.
💡Peak flow is typically mid-May through early June — call the park visitor center for current conditions before visiting.
Annual astronomy event held at one of Colorado's darkest skies, featuring telescope viewing, ranger-led programs, and constellation tours at Great Sand Dunes National Park.
💡Bring red flashlights to protect night vision and arrive before dark to secure a good spot on the dune field.
The NPS waives entrance fees at Great Sand Dunes National Park on the agency's birthday, August 25th, encouraging families to visit and celebrate America's public lands.
💡This is one of the busiest days of summer — arrive by 8am to find parking and secure a sandboard rental from nearby outfitters.
Great Sand Dunes National Park waives entrance fees on National Public Lands Day, inviting families to explore the tallest dunes in North America at no cost.
💡One of the best times to visit with older kids who can hike High Dune — start early to beat afternoon heat.
Held about 45 minutes from the dunes in Monte Vista, this festival celebrates the migration of 20,000+ sandhill cranes through the San Luis Valley with guided tours, speakers, and family activities.
💡Combine a crane festival visit with a stop at Great Sand Dunes for an unforgettable San Luis Valley weekend — cranes are most active at dawn and dusk.
As conditions improve in late winter and spring, local outfitters like Kristi Mountain Sports reopen sandboard and sand sled rentals, making the dune slopes accessible for family thrills.
💡Sand sledding is easier for younger kids than sandboarding — rent sleds rather than boards for children under 8.
Park rangers host special programming and activities for children to earn their Junior Ranger badges, with guided nature walks and hands-on exhibits at the visitor center.
💡Kids ages 5–12 get the most out of this — pick up the Junior Ranger booklet at the visitor center at any time of year as well.
Park rangers lead free guided walks across the dune field, sharing geology, ecology, and the cultural history of the San Luis Valley and Sangre de Cristo Mountains.
💡Bring water, sunscreen, and closed-toe shoes — the sand can exceed 150°F in summer afternoons so the morning timing is ideal for kids.
Nightly campfire programs at Pinyon Flats Campground amphitheater cover topics like dune formation, local wildlife, and dark sky astronomy.
💡Bring layers — temperatures drop dramatically after sunset even in summer — and let kids roast marshmallows after the program.
Local farmers and artisans gather in downtown Alamosa (30 minutes from the dunes) to sell San Luis Valley produce, crafts, and prepared foods including green chile and local honey.
💡Stop here before heading to the dunes to grab snacks and lunches — the Olathe sweet corn and green chile in season are worth the detour.
Rangers at the Great Sand Dunes Visitor Center run structured Junior Ranger activities for children including sand science experiments, wildlife tracking, and nature journaling.
💡Check the visitor center bulletin board upon arrival for the weekly schedule — programs vary and some days include special guest speakers or hands-on demonstrations.

Local Tips for Families
- 💡Rent sand sleds from Kristi Mountain Sports in Alamosa rather than buying disposable plastic ones — their rental sleds are heavier and actually slide better on the dry afternoon sand than cheap disc sleds. Return them same-day for a partial refund.
- 💡Check the Medano Creek flow status at nps.gov/grsa before your trip — creek flow peaks in late May and drops sharply after mid-June most years. Arriving even one week too late means finding dry sand instead of the famous wave surge that kids go wild for.
- 💡Hike to the ridgeline of High Dune (the closest major summit at about 650 feet) before 9am in summer — the sand surface is cool enough to walk barefoot before 10am, and you'll have the ridge nearly to yourself before the parking lot fills.
- 💡The free evening ranger programs at Piñon Flats Campground amphitheater run Friday and Saturday nights in summer starting around 8:30pm — topics rotate weekly between dune geology, San Luis Valley Indigenous history, and wildlife. These are genuinely excellent and appropriate for kids ages 5 and up.
- 💡Drive the 4WD Medano Pass Primitive Road north into the Sangre de Cristo Wilderness for a completely different perspective — the first mile along the creek is passable in most high-clearance vehicles and gives families a shaded, creek-side picnic spot away from the main dune crowds.
- 💡Pick up the Junior Ranger booklet at the Visitor Center on day one — completing it takes most of the trip and gives kids structured activities including a specific dune measurement challenge and a Medano Creek observation sheet that make the science feel real.
- 💡The dune surface temperature peaks around 2–3pm and then drops rapidly after 5pm — some families skip the afternoon entirely, nap at camp, and return to the dunes from 5–7pm when shadows from the Sangre de Cristos cool the sand and the light is spectacular for photos.
- 💡Stop at the Great Sand Dunes Oasis just outside the park entrance — beyond the basic camp store, they rent sand boards (longer and faster than sleds for kids over 8), have a small pizza window, and are the last place to buy firewood before entering the park.
