Most Dog-Friendly National Parks in the U.S.

Many national parks offer ample opportunities for you and your dog to enjoy together.

America’s national parks have always been popular vacation spots. In fact, visitation to the national parks in 2019 exceeded 300 million visits for the fifth year in a row. And while travel restrictions may have slowed things down for 2020, the wide-open spaces and fresh air of national parks are still drawing travelers eager to get back on the road.

But what if you have your four-legged best friend in tow? America’s national parks are notorious for their strict pet policies to ensure all national park visitors are safe and that the local flora and fauna are well preserved. Most parks require pets to be kept on a leash no longer than 6 feet, while many only allow pets in paved areas and developed campgrounds.

That doesn’t mean you can’t take Scout with you on the road, though. There are still many national parks that offer ample opportunities for you and your pup to enjoy together. Of the 422 units managed by the National Park Service, these 35 national parks, seashores, lakeshores, rivers and monuments tend to be a bit more lenient with where and how dogs can enjoy the Great Outdoors. Just see for yourself.

Northern California’s Yosemite National Park is one of the greatest wilderness treasures in the United States. It has 1,200 square miles of protected area, from plunging waterfalls, deep valleys, towering sequoias and thousands of years of glacial activity.

The Wawona Meadow Loop is a 5-mile flat path through one of the park’s biggest meadows, powdered with wildflowers and perfect for strolls. Pups can also go on the Mirror Lake Trail, a paved path that runs for 1 mile and passes underneath the base of Half Dome.

Petrified Forest National Park

The Petrified Forest National Park in Arizona is an other-worldly look back in time. Covering 346 square miles, it’s named for its deposits of petrified wood, desert and rainbow-colored badlands.

Not only are dogs welcome in Petrified Forest National Park, the park has its own special program designed for them. The BARK Ranger program is a special program specifically designed for dogs to enjoy the national park. It’s essentially an agreement you sign that ensures you will keep your dog leashed and respect the wildlife. But in exchange, dogs are given treats and special pet tags while they are in the park.

The best part about the Petrified Forest National Park is that all trails are dog-friendly. One of the best is the Big Logs Trail, which is a gravel nature walk that starts right behind the Rainbow Forest Museum. The Blue Forest Trail is one of the more adventure-driven, which has massive increases in elevation and is far less trafficked.

One caveat: Temperatures at White Sands National Park can get as high as 100 degrees Fahrenheit, so be sure to keep yourself and your pet well hydrated. Because of the extreme temperatures, it is important to not leave your pet in your car.

Badlands National Park

Reminiscent of a lunar landscape, Badlands National Park in South Dakota is about as stark and beautiful as it gets. More than 244,000 acres of prehistoric hills contain the secrets of thousands of years of fossil history. Contrasted to this are endless miles of mixed grass prairie, home to bison, bighorn sheep and prairie dogs.

But Badlands National Park is more than just a mesmerizing, haunting stretch of landscape for human eyes. Dogs can make the most out of the experience as well. Leashed pets are allowed on park roads, including the back country dirt roads, which is rare for national parks. Consider the Old Northeast Road north of Cedar Pass. The fully functioning ranch road takes visitors deep into the prairie, away from the highway.

Bryce Canyon National Park

Utah’s Bryce Canyon National Park showcases some of the most stunning natural beauty of America’s Southwest.

Bryce Canyon National Park may not be the most pet-friendly, but it certainly isn’t the least. Pets are permitted on all paved areas in the park, from campgrounds and parking lots to paved roads, paved viewpoints and the paved trail between Sunset and Sunrise Point. Unfortunately, dogs are not permitted on any unpaved surfaces.

For a bit more intrepid adventure, dogs and their owners will have the run of the land at nearby Red Canyon, which has trails that are pet-friendly. Red Canyon is managed by the U.S. Forest Service.

Crater Lake National Park

Formed 7,700 years ago, Crater Lake is the result of a volcanic eruption, which caused a towering peak to fall inwards. Over the millennia, it was fed by rain and snow and today is the deepest lake in the U.S.

Dogs are certainly welcome at Crater Lake National Park, but with a few guidelines. Aside from the ubiquitous leash rule, pets are only allowed on paved roads, in parking lots and up to 50 feet away from paved areas. Dog owners prefer to walk their dogs along the promenade at Rim Village, which has stunning views of the lake.

Pets are allowed on a few other hiking trails, though these do not have lake views. These include The Godfrey Glen Trail, The Lady of the Woods Trail, The Grayback Drive and The Pacific Crest Trail.
