If you’re dreaming of a family getaway that blends adventure, nature, and pure fun, look no further than Great Sand Dunes National Park in southern Colorado. It’s one of those magical places where kids can run wild, parents can breathe deeply, and everyone feels like a kid again.

You’ll stand in awe as you look out across a sea of golden dunes stretching toward the snow-capped Sangre de Cristo Mountains. The park feels like nature decided to create a playground just for families. One where you can sled down dunes, splash in creeks, and stargaze under skies so clear they’ll take your breath away.

As a travel advisor who’s sent countless families here (and explored it myself), I can promise you… There’s no place quite like it. So, grab your hats, pack your sunscreen, and let’s explore the best things to do in Great Sand Dunes National Park that will make your family vacation unforgettable.

Unforgettable Things to Do in Great Sand Dunes National Park: A Family Adventure in Colorado’s Sandbox Wonderland

Climb to the Top of the Tallest Sand Dune – One of the Best Things to Do in Great Sand Dunes National Park

You can’t visit Great Sand Dunes without climbing the dunes. And yes, they’re even more spectacular than they look in pictures!

The tallest, known as Star Dune, rises an impressive 750 feet. This makes it the tallest sand dune in North America. The trek to the top and back takes about five hours round trip. And trust me, you’ll feel every step in the soft sand.

But the payoff? A sweeping 360-degree view that makes the effort completely worth it.

If you have younger kids or just want something less strenuous, I always recommend heading to the High Dune instead. It’s a bit closer to the parking area and still offers jaw-dropping views without the marathon climb.

Either way, remember, bare feet work best on the dunes. Especially in the cooler morning or evening hours.

Sled or Sandboard Down the Dunes

Forget snow! Here, it’s all about sand sledding!

Rent a sandboard or sand sled from nearby shops in Alamosa or at the park’s entrance. (The Visitor Center can point you in the right direction). You’ll climb up the slopes, hop on, and zip down the silky sand like its winter in July.

I always tell my clients to visit in the morning when the sand is still cool. In summer afternoons, it can reach over 140°F. So, early starts are key.

And don’t forget your sense of humor. Falling in sand is half the fun!

Splash and Play in Medano Creek

From late May through early July, Medano Creek transforms the base of the dunes into a shimmering natural water park.

Your kids will love wading through the ankle-deep waves. Building sandcastles. And chasing the “surge flow” (that’s when waves ripple downstream like mini ocean tides).

Bring water shoes, floaties, and a picnic lunch. You’ll want to stay a while.

If you visit in midsummer, the creek may dry up. But there’s still plenty of fun to be had exploring the sand and nearby trails.

Pro tip from me: Plan your trip during Medano Creek’s peak flow for the ultimate family experience. It’s one of the most unique natural phenomena in Colorado.

Join a Ranger Program – An Educational Thing to Do in Great Sand Dunes National Park

The park rangers at Great Sand Dunes are full of fascinating stories and insights that make the park come alive.

I always encourage families to join at least one ranger-led program. Whether it’s a guided nature walk, a Junior Ranger activity, or an evening stargazing talk.

Programs are typically offered Thursday through Saturday, but schedules change seasonally. So, check the Visitor Center when you arrive.

My personal favorite? The Sunset Hike with a Ranger. Watching the dunes shift from gold to deep orange as the sun dips behind the mountains is pure magic.

Hike to Zapata Falls

Just a short drive from the main park entrance, Zapata Falls offers a refreshing break from the sand.

The trail is an easy half mile walk each way, making it perfect for families. You’ll hike through rocky terrain and step into a cool crevice where a 30-foot waterfall tumbles into a small pool.

It’s especially rewarding on a hot summer day. Just don’t forget water shoes for the creek crossing!

I often recommend stopping here either before entering the park or on your way out. It’s a quick adventure that’s well worth the detour.

Go Off-Roading on Medano Pass Primitive Road

Ready to kick things up a notch during your Great Sand Dunes National Park family vacation?

If you’re traveling with older kids or teens, rent a 4WD vehicle in nearby Alamosa and take on Medano Pass Primitive Road. This 22-mile route connects the park to Wet Mountain Valley. It features soft sand, creek crossings, and jaw-dropping mountain scenery.

You’ll need to air down your tires for traction (the Visitor Center can help with guidance). Along the way, you’ll find picnic spots and primitive campsites that feel a world away from modern life.

It’s rugged, wild, and absolutely unforgettable. One of my top recommendations for adventurous families.

Stargaze Under a Blanket of Stars

Great Sand Dunes National Park is a certified International Dark Sky Park, meaning the stargazing here is out of this world—literally.

On a clear night, you’ll see the Milky Way stretch across the sky like a river of diamonds. Bring a blanket, lie back on the cool sand, and let your kids pick out constellations.

If you’re visiting in summer, plan your stargazing on a moonless night for the best visibility. I often tell families to stay after sunset. It’s quieter, cooler, and simply magical.

Discover Hidden Hiking Trails Beyond the Dunes

While the dunes get all the attention, there’s so much more to explore.

Trails like Mosca Pass Trail wind through forested slopes and wildflower meadows, offering a completely different side of the park. It’s about a 7-mile round trip, and the shade makes it perfect for a midday hike.

For younger kids, the Dunes Overlook Trail is a great choice. It’s short (just 2.3 miles round trip) but rewards you with panoramic dune views. I often recommend combining it with a picnic lunch for a relaxed afternoon.

Explore Nearby Attractions and Towns

After your dune adventures, spend some time exploring the surrounding area.

Head into Alamosa, the gateway town, where you can grab a hearty family meal and visit the San Luis Valley Museum. Or hop aboard the Rio Grande Scenic Railroad for a different view of the mountains.

If you have extra time, consider a day trip to the Colorado Gators Reptile Park (kids love it!). Or the Fort Garland Museum for a bit of history and fun.

Stay Nearby for the Full Experience

There’s nothing quite like waking up to the sight of the dunes glowing gold in the early morning light.

Look for accommodations in Alamosa or Fort Garland. Many offer mountain views, family suites, and modern amenities while keeping you close to the park.

Best Time to Visit Great Sand Dunes National Park

Each season brings its own kind of beauty to Great Sand Dunes.

• Spring (April–May): Medano Creek begins to flow, and the dunes are still cool enough for midday exploration.

• Summer (June–August): Perfect for water play in the creek and warm evenings for stargazing. But start activities early to avoid the midday heat.

• Fall (September–October): Cooler temps and fewer crowds make this my personal favorite time for family visits.

• Winter (November–March): Quiet, peaceful, and surprisingly beautiful. Just dress in layers, as temperatures drop quickly after sunset.

If you want to experience the dunes at their best, I recommend late May through early June for the perfect mix of creek fun, manageable temps, and wildflower views.

Weather & What to Pack

The weather here can shift quickly. From sunny and hot on the dunes to breezy and cool in the mountains.

Here’s what I always suggest packing:

• Light layers: Mornings and evenings are cool, while midday heat can be intense.

• Sun protection: Hats, sunglasses, and plenty of sunscreen.

• Water shoes or sandals: For Medano Creek and Zapata Falls.

• Closed-toe hiking shoes: For off-road trails or rocky terrain.

• Reusable water bottles: Dehydration happens fast in the dry mountain air.

• A bandana or face cover: Windy days can kick up sand.

I tell all my clients to pack for both desert and mountain conditions, because you’ll experience a bit of each!

A trip to Great Sand Dunes National Park isn’t just another family vacation. It’s an experience that sticks with you. You’ll laugh as you tumble down dunes, marvel at the stars together, and make memories that last a lifetime.

Whether your kids are chasing the waves of Medano Creek or your teens are snapping selfies from Star Dune’s summit, this park offers something truly special for every generation.
