6 dog-friendly National Parks that are great for hiking

Dogs are family and family adventures are the best kind! Many National Parks are dog-friendly, but only allow dogs on a couple select trails. The six included included in this post are some of the least restrictive in terms of where your dog can hike within the park’s boundaries. In fact, they welcome and encourage furry friends to enjoy the park’s hiking trails alongside you.

Why many National Parks strictly regulate dogs

Most national parks are not dog-friendly due to concerns for wildlife, ecosystems, and visitor safety. Dogs can disturb or harass wildlife, spread diseases, and damage fragile environments. They also pose risks to other visitors, especially in busy or hazardous areas. While some parks allow pets in designated areas or on specific trails, the overall restriction is to protect both animals and the natural landscape, ensuring a safe and enjoyable experience for all.

But the parks included in this post do allow and even encourage dogs to hike their trails, which makes them some of our favorites!

BARK Ranger Programs at National Parks

We first discovered the whole BARK Ranger phenomenon while waiting out a storm at Pecos National Historical Park. A ranger spotted us, asked us if we were BARK Rangers, and when we had no idea what he was talking about, he opened the door to a whole new world! He recited the BARK Ranger principles with us, and then presented Bonnie & Ada with collectible tags, specific to Pecos. It was adorable, and super sweet! And we have not stopped chasing BARK Ranger Parks since.

BARK Ranger programs only exist at some National Parks, and there is a lot of diversity park-to-park in terms of what their programs entail. The common thread is the principles (below), which a ranger will always review with you when you ask about the program. Sometimes there are activities to complete with your dog. Sometimes you are simply given a piece of paper that lists the principles. Sometimes they will gift you a special tag, and sometimes they will direct you to the gift shop where you can buy a tag. Some parks have other special BARK Ranger merch – Bryce Canyon has BARK Ranger patches for sale, while Hot Springs has an array of different BARK Ranger Bandanas, dog toys, and other little goodies in their gift shop. Indiana Dunes has tags for sale, but will give you a bandana for free when you ask a ranger.

The bottom line is that participating parks differ because it’s basically just up to a staff member to create the BARK Ranger program they want to see in their park. So a good rule of thumb is to simply always find a ranger and ask:

  • Do you have a BARK Ranger program at this park?
  • I have a dog who would like to be a BARK Ranger – What’s involved?
  • Do you gift BARK Ranger tags or other merch? Or do you have some for purchase in the gift shop?

BARK Ranger Principles

  • Bag your pets’ waste. Help keep your national park clean by collecting and disposing of all dog waste. Public garbage cans are located throughout the park, including at the visitor center.
  • Always keep your pet on a leash. For the safety and comfort of all the park’s visitors, dogs must be restrained on a leash no longer than 6 feet. We know that sometimes Fido likes to run free, but keeping dogs on leashes will also protect them from ticks, snakes and other wildlife, and other dogs.
  • Respect wildlife. The park is also home to snakes, birds, rabbits, deer, and other wildlife. Pets can harass or harm wildlife by making noise or scaring wildlife away. Please keep your dog at a respectful distance from any animals you may encounter.
  • Know where you can go. Pets are not allowed inside park facilities, including the visitor center. However, the national park is home to 26 miles of trails that dogs (and their humans) love!

1. Great Sand Dunes National Park, Colorado

BARK Ranger Program: YES

Great Sand Dunes National Park is a stunning collision of sand and mountains, surrounded by juniper and pinion forest.

The Great Sand Dunes were formed through a complex combination of geological and environmental forces. The uplift of surrounding mountain ranges created the San Luis Valley, where ancient lakes once deposited sand. As the lakes receded, winds and seasonal storms sculpted the sand into towering dunes, with the area’s unique geography funneling the sand into its current configuration. The seasonal streams, like Medano and Sand Creeks, continue to reshape the dunes, preventing them from advancing into the mountains. This ongoing natural process has produced the tallest sand dunes in North America.

The park is home to a diverse array of wildlife adapted to its extreme environment. Amphibians such as tiger salamanders and chorus frogs have developed the ability to freeze during winter and return to life in the spring. Other species, including northern leopard frogs and spadefoots, thrive in the park’s wetlands and dunes. Among the mammals, Ord’s kangaroo rats live in the dunefield year-round, using the sand for shelter and moisture. Over 250 bird species, including iconic sandhill cranes, are found in the park, making it an important migration stop. The park’s ecosystems range from alpine tundra to wetlands, providing habitats for a wide variety of species in this unique, high-altitude desert landscape.

🐾Dogs are allowed on many trails & dunes, but are prohibited from wilderness areas. Check the park’s website for specific inclusions/exclusions.

Why we love Great Sand Dunes

Great Sand Dunes National Park is  truly spectacular! I’ve lived in Colorado for many years, and until a few years ago, only drove past this park and marveled from afar. After we adopted Bonnie and Ada, I resolved to get to all of Colorado’s parks, and this was top of our list! 

Miles of sandy terrain means endless opportunities for dogs to dig, run, bounce, and climb. This is one of the least restrictive national parks in the US for dogs, and it’s a true gift. The park looks beautiful under a blanket of fresh snow, so it’s ideal to visit in winter. But it truly comes alive when Medano Creek gushes down from snow melt in the early summer, creating a beachy atmosphere in the park. You’ll probably want to avoid visiting in high summer, because sand temperatures get really high. But evening and early morning visits are fine if this is the only time you can make it. 

In addition to climbing and hiking around the dunes, the park also includes mountain trails that your dog is welcome to hike. In short, this park is a complete dog-friendly paradise year-round, and I promise you will be completely blown away by the beauty.

2. White Sands National Park, New Mexico

BARK Ranger Program: YES

White Sands National Park is absolutely breathtaking.

White Sands National Park, known for its stunning gypsum dunes, showcases millions of years of geological evolution. Over 250 million years ago, gypsum was deposited in the Permian Sea, and through tectonic shifts and climatic changes, the Tularosa Basin formed, eventually giving rise to the white sand dunes seen today. These dunes are continually reshaped by wind and erosion, creating a dynamic landscape. Over time, many animal species adapted to the white environment, evolving lighter colors to blend into the dunes, providing a survival advantage.

The park is home to more than 800 species, including several unique to the area. Notable residents include the light-colored Apache pocket mouse, bleached earless lizard, sand-treader camel cricket, and sand wolf spider. The park also hosts a remarkable variety of endemic moths—about 40 species—that have evolved to thrive in the gypsum-rich environment. These animals, many nocturnal, have developed specialized survival strategies for the harsh conditions, making White Sands a fascinating example of evolution in action.

Why we love White Sands

White Sands is truly incredible. This park transports you to a place so unlike anything else in this world, you can’t help but stand in awe. Much like the Great Sand Dunes, this park has miles and miles of sand dunes for you and your dog to explore by climbing, sliding, digging, running, bounding, and rolling. The possibilities are endless. 

We suggest planning your trip so you catch a sunset, because the light bouncing off the white sand is like nothing I’ve ever seen before! This is another great park to visit in the winter time, to avoid extreme heat, but it is truly beautiful year-round as long as you plan ahead and be conscientious about your dog’s needs.

Hot Springs National Park in Arkansas is a geological and ecological gem, located within the Zig-Zag Mountains of the Ouachita range. The park’s rugged terrain, shaped by tectonic forces 300 million years ago, features folded and tilted layers of sandstone, shale, chert, and novaculite. Rainwater, falling on the recharge zones, seeps into fractures and travels deep underground, heating up due to the Earth’s geothermal gradient. After thousands of years, the water emerges along Bathhouse Row at a temperature of 143°F, bringing minerals like calcium, magnesium, and potassium, which form tufa as the water cools.

The park’s diverse habitats, from dense forests to rocky slopes and creek valleys, support over 50 mammal species, including white-tailed deer and groundhogs, as well as more than 100 bird species. It also hosts 50 fish species and over 70 types of reptiles and amphibians, including snakes, turtles, and salamanders. Wildlife is most active at dawn and dusk, with winter offering clearer views of the animals as the trees shed their leaves.

🐾Dogs are allowed on ALL trails in the park, but check the park’s website for specific considerations.

Why we love Mammoth Cave

Mammoth Cave is such an interesting park. Of course the main attraction is the miles and miles of underground caverns, which can only be explored via a pre-booked tour. And dogs are not allowed on those. So what is the park doing on this list? The park also includes miles of above ground trails, and dogs are allowed to hike them all! 

The above-ground park is a blend of hardwood forests, riverside views, and historic sites, and we especially love visiting during wildflower season! 

The cave tours are incredible, and there are many different options to choose from. Conveniently, the Lodge at Mammoth Cave offers dog-friendly lodging, as well as day boarding, so your dog will be well taken care of while you explore the cave. The Lodge is right next to the visitor center, so it’s all quite easy to manage if you plan your trip ahead of time.
