The Rocky Mountains are one of the last places you’d expect to find a desert landscape. Natural forces, evaporating lakes, and prevailing southwestern winds created the dune field that attracts hundreds of thousands of visitors each year – and their pets!

So, is Great Sand Dunes National Park dog-friendly? Absolutely! Pets are allowed in the following places in the National Park:

• Most trails, except the sand ramp trail and the backcountry dune field
• The Main Use area
• Medano Pass primitive road
• Campgrounds
• Picnic Areas

Great Sand Dunes National Park and Preserve is an otherworldly landscape in southcentral Colorado. It’s a fantastic destination for you and your pet to explore exceptional hiking trails and dunes, splash in creeks, and take in the beauty of the surrounding Sangre de Cristo mountains together.

Quick Tips For Visiting Great Sand Dunes National Park With A Dog

National Parks get a bad rap for not being very pet-friendly. However, parks like Great Sand Dunes are pretty welcoming to our furry pals! With that in mind, there are a few specific things concerning Great Sand Dunes National Park dog-friendly policies:

• Sand Temperature: In the summer, sand in the park can reach scalding temperatures of up to 150℉. Plan hikes with your pet in the early morning and consider getting them a pair of booties like Ruffwear Grip Trex Dog Boots to protect their paws from the hot sand.
• Cactus Spines: The grasslands surrounding the dunes and the park may have prickly pear and other cactus species that can injure your pet’s paw pads. Again, consider getting them a pair of sturdy dog boots to protect their paws. Always carry a rescue sling like the Fido Pro Airlift Emergency Dog Rescue Sling if you need to carry your pet back to the car. We have a fantastic guide to the best dog rescue slings here if you need help choosing!
• Water: At the visitor center, you and your pup are standing at 8,170 feet elevation. Bring plenty of water to combat the elevation and dry air around Great Sand Dunes National Park. I highly recommend a dog water dish like Frisco Silicone Collapsible Travel Bowl. We also have a comprehensive list of our favorite portable dog water bowls for hiking here!
• B.A.R.K. Ranger Program: Be sure to ask about the BARK Ranger Program at the visitor center. You’ll be rewarded with a nifty badge for your furry pal!
• Leash Policy: Your furry pal may be extremely well-behaved, but they must always be kept on a leash in the park. Check out our guide on the best dog leashes for hiking to see our top picks!
• Pet Waste: Always pick up your pet’s poo, even if they go well off the trail or in the woods. Dog poo can transmit diseases to other canines in the area, like foxes and coyotes, and disrupt the natural patterns established by wild animals. Grab a stack of poo bags like Earth Rated Dog Poop Bags.
• Afternoon Thunderstorms: Ask any Colorado native, and they’ll tell you to be ‘off the mountain’ by early afternoon. During the summer, afternoon thunderstorms often occur, bringing lightning and hail. Remember, when you’re standing on the dunes, you are the tallest object around for miles. If you hear thunder or see lightning, get off the dunes immediately.
• Bugs: The Great Sand Dunes National Park mosquitoes are legendary, but not in a good way. In the summer, prepare for high levels of these blood-sucking pests. While they’re not heavily present on the dunes, they are everywhere in the parking lots and other trails. Make sure your pup is protected from heartworm, which is transmitted by mosquitoes.

Now, let’s discuss all the details of Great Sand Dunes National Park dog-friendly policies!

7 Dog-Friendly Trails At Great Sand Dunes

Hiking with your furry pal is one of the best experiences in a National Park. It’s an opportunity to bond with your pup and exercise simultaneously! Your dog will love all the new sights, sounds, and smells, and you get to enjoy seeing their tail wagging non-stop.

Below are the hiking trails that allow dogs according to the Great Sand Dunes National Park dog-friendly policy.

1. Main Use Area: High Dune

Hiking in the Main Use Area of Great Sand Dunes National Park is a must-do with your dog. This is the main dune field where you and your pup can hike anywhere. Seriously! There aren’t any trails in the dune fields, so you can pick a direction and start walking amongst the dunes!

One of the most popular things to do in this area is hiking High Dune. It’s not actually the tallest Dune in the park; that title belongs to Hidden Dune, the tallest Dune in North America, at 741 feet! However, it offers exceptional views of the surrounding backcountry dunes.

From the base to the top, it’s a 688-foot climb up a sandy dune, so ensure you and your pup are up for the challenge. Bring plenty of water and sunscreen, and make sure you go in the morning or evening so the sand doesn’t burn your dog’s paws!

It typically takes 2-4 hours to hike this Dune.

• Where To Park: Park at the Dunes Parking Lot (N37.7396, W105.5170)
• Length: Approximately 2.5 miles out-and-back

As mentioned previously, there are no trail markers in the dunefield. High Dune is the tallest Dune you can see from the Dunes Parking Area. It may help to pin the coordinates on a mapping app before starting the hike to ensure you summit the correct Dune.

2. Sand Pit and Castle Creek

The Sand Pit and Castle Creek hiking trails are north of the Main Use Area. Depending on what type of vehicle you drive, you can park directly at the picnic areas (4WD) or at the Point of No Return lot and hike to the picnic areas along the trail.

Even if you have a 4WD vehicle, I recommend the latter option because it gives you and your furry pal a chance to hike in the beautiful scenery offered by this National Park.

• Where To Park: Point of No Return parking lot (N37.7581, W105.5012)
• Length: 1.5 miles out and back from the parking lot to Sand Pit. 3 miles from the parking lot to Castle Creek.

Sand Pit and Castle Creek offer access to Medano Creek, which can be a refreshing dip for you and your pup. This broad and shallow creek is typically dry in the summer but may flow gently in the spring and fall. There is also an impressively steep dune face at Castle Creek that offers fantastic photo opportunities.

3. Montville Nature Trail

The Great Sand Dunes National Park dog-friendly policy allows pets on this short but rewarding hike on the park’s eastern side, away from the dune field. At the highest point on the trail, you and your four-legged friend will stand at 8,350 feet elevation and have spectacular views of Mt. Herard in the Sangre de Cristo Mountains and the dune field.

This trail is a fantastic way to escape the heat. It meanders along Mosca Creek under a canopy of piñon pine, aspens, and Douglas fir.

• Where To Park: Just past the visitor center is a paved parking lot on the right. (N37.7341, W105.5086)
• Length: 0.5-mile loop

This trail was named for the 1800s settlement that resided here: Montville. Back then, about 20 houses called this area home! This trail can get pretty buggy at the height of summer, so bring bug spray and ensure your pup is up-to-date on heartworm medication! We use Interceptor Plus, and it gives us so much peace of mind knowing our dog, Pawdrick, is protected against heartworm, which can be debilitating.

4. Mosca Pass Trail

If you and your canine companion are up for a more challenging hike, the Mosca Pass Trail leads to a low pass in the Sangre de Cristo Mountains. An elevation gain of around 1,400 feet makes this trail more challenging than the others, but well worth the effort!

The trail is generally uphill on the way to the pass and downhill on the way back. The pass is around 9,600 ft in elevation, so bring plenty of water for you and your pup.

• Where To Park: Park at the same lot as the Montville Nature Trail (N37.7341, W105.5086).
• Length: 6.2 miles out and back

Most of the trail follows a small creek protected by towering pine trees and aspen groves, offering shade on hot days. In the summer, the trail may be plagued with mosquitoes. 

5. Wellington Ditch Trail

The Wellington Ditch Trail connects the Mosca and Montville Trails parking lot to the Piñon Flats Campground. The trail offers varying terrain, shifting from grassy plains to arid desert. In the spring and summer, you can catch blooming flowers along the trail with the towering dunes as a backdrop.

This trail has limited shade, so choose what time of day you hike wisely. Aim for morning or evening to avoid the hottest temperatures.

• Where To Park (Two Options):
  • Mosca and Montville trailhead lot (N37.7341, W105.5086).
  • Paved lot beyond the Piñon Flats Campground (N37.7441, W105.5031).
• Length: 2.3 miles out and back.

The trail has minimal elevation gain, making it an excellent option for older pups or those new to hiking. I highly recommend wearing sunscreen and a sun hat to avoid the harsh sun on this open trail. 

The Great Sand Dunes National Park dog-friendly policies also state that cacti are present in the grassland areas around the park, so stay vigilant to ensure your pup’s paw pads don’t get pricked!

6. Dunes Overlook Trail

As the name suggests, this trail ends at an overlook offering awe-inspiring views of the dunes from around 8,600 feet. The trail is steep towards the end but gently sloping during most of the hike. 

At the turnaround point, you’ll find benches to sit on and soak in the beautiful views of the dune field and the picturesque San Luis Valley below.

• Where To Park (Two Options): 
  • Paved lot before campground (N37.7437, W105.5067).
  • Paved lot after campground (N37.7441, W105.5031).
• Length: 2.7 miles out and back

You and your pup will love exploring this trail. It’s a great option if your dog enjoys a little more solitude and doesn’t do well with other dogs or people, as this trail is less popular than others around the park. If you have a reactive dog, we have an excellent guide for hiking with a reactive dog, including tips and support for reactive dog guardians!

7. Medano Pass Primitive Road

The Medano Pass Primitive Road is an 11.2-mile-long road accessible only by high-clearance 4WD vehicles in the summer. However, it’s also a fantastic hiking opportunity for you and your canine companion!

The road crosses Medano Creek in nine different places and is excellent for spotting wildlife like bighorn sheep. Medano Pass connects Great Sand Dunes National Park with Colorado State Highway 69. You and your pup can walk as long or as short as you want, enjoying the beautiful views. 

Since the road requires specific vehicles, it doesn’t see as much traffic as the main park roads. The traffic that you do see will be moving slowly over the rough terrain, giving you and your pup plenty of time to move to the side of the road to let them pass.

• Where To Park: Paved parking lot near the start of Medano Pass (N37.7437, W105.5067)
• Length: 22.4 miles out and back

Alternatively, if you have the right vehicle type, park on the pull-offs or picnic areas, such as Sand Pit and Castle Creek, and hike from there.

On a side note, Great Sand Dunes National Park isn’t the only pet-friendly park in the West. Check out our list of the 10 best dog-friendly National Parks in the West for a complete list!

2 Pet-Friendly Campgrounds At Great Sand Dunes NP

Great Sand Dunes National Park dog-friendly policies state that there are two pet-friendly camping areas in the park: Piñon Flats Campground and Medano Pass Primitive Road camping. 

Unfortunately, pets are prohibited in any backcountry dunes, so you cannot backcountry camp with your pup at Great Sand Dunes.

Piñon Flats is a good choice if you have an RV or campervan and want to be close to the park’s central area. However, be aware that the campground is typically packed at all times during the peak summer season, so you’re unlikely to find solitude or quiet nights here.

The Medano Pass Primitive Road is only accessible by 4WD vehicles with high clearance. If your car can handle it, this is an excellent opportunity to camp in solitude in the Great Sand Dunes National Preserve. Your only companions will be your furry pal and a magnificent star-filled sky each night.

1. Pet-Friendly Camping At Piñon Flats Campground

Piñon Flats Campground is past the visitor center and the main dune field. A spot can be booked up to 6 months in advance, and peak seasons are late spring and early summer when Medano Creek is flowing.

The campsites vary in size and space, but each site can accommodate a maximum of 8 people, 2 tents, and 2 vehicles. When you book your stay through recreation.gov, they list site-specific measurements so you can make sure your vehicle and/or tents will fit within the site. They also provide photos of each site so you know what to expect.

There are no electric hookups at Piñon Flats Campground. A dump station and hose are only available in the summer months.

• Location: Follow the main park road, which ends at the campground (N37.7445, W105.5054).
• Price Per Night: $20
• Number of Sites: 91
  • RV (55 sites)
  • Tent Only (33 sites)
  • Group Sites (3 sites)
• Vehicle Max Length: 35 feet (only a few sites accommodate this length).
• Amenities: 
  • Campground: Restrooms, dishwashing sink, potable water spigots, trash dumpster, recycling station, store with limited supplies.
  • Individual Sites: Fire grate, picnic table, bear box.

Some sites have small trees and shrubs, while others are open with views of the dune field. Check each site carefully before selecting, and then enjoy a wonderful stay in a National Park with your furry pal!

2. Watch The Stars With Your Dog At Medano Pass Primitive Road Camping

Camping on the Medano Pass Primitive Road is an excellent way to experience the park’s beauty without the crowds and annoying whirring generators of a campground. However, you’ll need 4WD and high clearance to access these campsites. 

Small SUVs will not make it. 

Unlike the Piñon Flats Campground, camping along Medano Pass Primitive Road is on a first-come, first-served basis. It may be challenging to find a spot on busy summer weekends, so it’s recommended to aim for weekdays during peak season if you want to snag a spot.

• Location: Turn left just before the Piñon Flats Campground to jump on Medano Pass Primitive Road (N37.7442, W105.5069)
• Price Per Night: Free
• Number of Sites: 21 (dry camping)
• Vehicle Max Length: N/A – 4WD vehicles only.
• Amenities: Fire ring, bear box.

Camping is only permitted in designated spots. You’ll know you’re at a campsite if you see a brown post with a camping symbol and a number. When dry camping, remember to Leave No Trace. Pack out everything you pack in, including toilet paper, food scraps, and any garbage you generate while camping.
