Grand Canyon National Park
Experience the grandeur of this stunning natural wonder with your dog along the 13 miles of the South Rim trail. Pets are not permitted below the rim of the Grand Canyon, but you can take your pooch for a stroll on any of the hiking trails that stay above the perimeter, which includes most of the spectacular South Rim Trail. If you want to experience one of most scenic trains rides in America on The Grand Canyon Railway, Fido can rest and relax at The Railway Pet Resort, the luxe air-conditioned animal hotel at the Grand Canyon Railway & Hotel (humans can spend the night at the hotel or campgrounds here as well).

Vast wilderness, expansive meadows, towering sequoias—this park is probably the image most people conjure when they think of national parks. Because of the wildlife that roams free here, dogs aren’t allowed deep into the park, but the Wawona Meadow Loop trail at Yosemite National Park is dog-friendly, and canines are also permitted on the park’s many roads, sidewalks, and bike paths. You can bring leashed pets to stay at all of Yosemite’s campgrounds, too, with the exception of hike-in (meaning those deep in the park) and group camps. Dan Wulfman, founder of Tracks and Trails, a company that plans RV vacations in national parks, suggests adding nearby pet-friendly Lake Tahoe to your Yosemite itinerary, where dogs can romp at Kiva Beach and Echo Lake and play off-leash at Bijou Dog Park.
