Are U.S. National Parks Dog-Friendly?

Do you love exploring the great outdoors with your furry best friend? Me too! But before you take your pup for a hike, you’ll want to make sure the park and trail are dog-friendly. 

The National Parks across the U.S. are truly majestic. Sadly, though, they do not all welcome dogs. And those that do, may only allow them on specific trails. We did a little research to make sure you know before you go.

Which National Parks Do Not Allow Dogs?

There are 63 National Parks across the United States, but only 16 of them allow dogs on some or all of their trails. And a few parks will allow dogs to accompany you in certain developed spaces of the park like a campground or picnic area—but not actually on the trails. 

Even though this may seem like a bummer for dog-lovers, there are still plenty of places you can bring your pup for a hike.

Why So Many National Parks Are Not Dog-Friendly 

Although we may not be too happy about our dogs not being allowed in all National Parks, they do have their reasons

  • Dogs bark and can scare or disturb the wildlife.
  • Dogs can chase wildlife away from their “nesting, feeding, and resting sites. A dog’s scent can signal the presence of a predator, which may alter the behavior of park wildlife. Small animals may hide in their burrow the entire day after smelling a dog and may not venture out to feed.”
  • If a dog gets off-leash or is uncontrolled, they can scare or harm other humans.
  • Dogs can carry disease into the wildlife population.
  • Dogs may become prey for larger animals. “If your dog disturbs and enrages a bear, it may lead the angry bear directly to you.”
  • Dogs can encounter poisonous plants or contract a disease from an insect bite.

Are Dogs Allowed in U.S. National Forests?

Great news: dogs are allowed in all 154 of the United States National Forests! You may not be as familiar with the National Forests as the National Parks, but don’t let that deter you from checking them out. These places are beautiful and offer ample hiking opportunities too. Many of them are located near a National Park, so you can enjoy both in one visit! 

Just remember to keep your dog on-leash—no more than 6 feet long—and always clean up after them. If you follow those simple rules, National Forests are incredibly dog-friendly. They’ll welcome your pup with open arms!

Which National Parks Are the Most Dog-Friendly? 

All of the National Parks listed below are great for dogs! Most of them will allow your dog to hike with you throughout the entire park. And those that don’t still offer a large number of dog-friendly hiking trails. The only dog-friendly National Park with only a handful of pet-friendly trails is Olympic National Park. Olympic does offer several dog-friendly hiking trails… just not nearly as many as the others listed below.

Check Out the B.A.R.K. Policy

As you plan out hikes to take with your favorite canine… make sure to read the National Park B.A.R.K. Policy, written out below. These four simple rules help keep everyone safe and keep our parks pristine.

  1. Bag Your Pet’s Waste
    Cleaning up after your dog helps keep the parks clean. Plus, your dog’s waste is a “non-native element” in the park’s ecosystem, and we want to respect the health and well-being of the wildlife.
  2. Always Leash Your Pet
    Pets must remain on-leash at all times, with a maximum leash length of 6 feet. This protects other wildlife, people, and canines from your dog (and vice versa!).
  3. Respect Wildlife
    Letting your dog approach any wildlife can be extremely dangerous. Depending on the park, you could encounter animals like grizzly bears, mountain lions, or rattlesnakes. So, you must have reasonable physical control over your dog’s leash and reliable voice control over your dog’s behavior.
  4. Know Where You Can Go
    Before you hit the trails, stop by the visitor center to ask the park rangers where dogs are allowed. Plus, it’s always a good idea to grab a map of the trails.
