Few landscapes throughout the U.S. can compare in uniqueness to Bryce Canyon National Park. This Utah park features the world’s largest concentration of hoodoos - tall, thin spires formed by erosion over millions of years. Fido is welcome to join you for an up-close look at these unique formations from paved trails, roads and overlooks throughout the park. Take your canine for a stroll along the paved path between Sunset and Sunrise Points which meanders along the rim of the canyon, stopping to admire jaw-dropping vistas along the way.

Rest up for the night just outside the park at Best Western Plus Ruby’s Inn and spend the next day visiting one of Utah’s other national parks, Zion, just two hours south of Bryce Canyon.

From the top of Devils Postpile National Monument in Mammoth Lakes, CA, it looks like someone has carefully laid hexagon tiles across the ground, while from below, a giant wall of symmetrical rock posts protrudes from the ground and rises 60 feet into the air. Pups are welcome to join you on the tram from the Mammoth Lakes Visitor Center to the trailhead if a muzzle is worn for the brief ride. Once there, Fido can tag along for a hike to the base of the basalt columns for incredible photo ops, and make the loop up to the top to see the rare geological wonder from above. He’s also permitted on the 2.5-mile hike to the 101-foot-high Rainbow Falls, aptly named because of the multitude of rainbows appearing in the mist on sunny days.

Book a room at Edelweiss Lodge and spend a weekend in Mammoth Lakes. Fido can join you for dinner and a brew at Mammoth Brewing Company and admire more views from the Mammoth Mountain Scenic Gondola.

If you’re hoping to hike, Voyageurs National Park in northern Minnesota may not seem all that dog friendly. Pets are only permitted on one trail, the 1.7-mile Rainy Lake Recreation Trail, which does offer great forest, lake and marsh views. But, more than one-third of the acreage in this park along the Canadian border consists of water, and Fido is welcome to join you on boats, kayaks or canoes throughout it. Take your adventurous pup for a paddle or a cruise to one of the 137 pet-friendly frontcountry campsites which are only accessible by water, and pitch a tent on your own private island. Each site includes a fire ring and a picnic table, and most have waterfront views where you can relax with your furry best friend and enjoy the seclusion of this northern paradise. Time your visit right and you might even spot the aurora borealis lighting up the night sky.

If you’d prefer a home base rather than a campsite, book the Lake Kabetogama Cabin instead. Admire lake views from the comfort of the bedroom, and take your morning coffee out to the dock to enjoy the sunrise with Fido.

When you make the hour-and-a-half desert drive from the Grand Canyon to Flagstaff, AZ, it’s hard to imagine a volcano erupting in the area, but that’s exactly what happened 1,000 years ago at Sunset Crater Volcano National Monument. Bring Fido along for a scenic detour to this wonderland of black rock, formed by lava flow, that covers the land. Start with a drive on the 34-mile scenic loop through ponderosa pine forests to red rocks and painted desert. Along the way, stop for a walk on the one-mile paved and pet-friendly Lava Flow Trail to get a closer look at this unusual landscape. Just make sure your pup sticks to the trail as the lava rock is jagged and can injure paws.

Pitch a tent just outside of the park at Bonito Campground or book a cabin at Basecamp at Snowbowl, and spend the next day exploring more lava fields from Sunset Crater on the neighboring and pet-friendly O’Leary Peak Trail in the Coconino National Forest.

There aren’t many places in the country where you and your pup can spot a 100 to 180-foot geyser erupt during a predicted time frame, but at Yellowstone National Park you certainly can. This national park that traverses three states - Wyoming, Montana and Idaho - contains some of the world’s most unique natural wonders, including Old Faithful. While Fido isn’t allowed on the trails or boardwalks within the park, he can join you in the shaded, paved areas near the Old Faithful Lodge and Cabins and visitor center, all within close viewing distance of the predictable geyser. Additionally, Yellowstone is home to other unusual geologic features like fumaroles and hot springs, many of which can be seen from a scenic drive around the Yellowstone Loop. Make sure your pooch keeps his eyes peeled for wildlife like bison, elk, moose and bears along the way.

Catch Old Faithful at different hours throughout the day when you stay in a pet-friendly cabin at Old Faithful Lodge and Cabins. Spend the following day driving through nearby Grand Teton National Park for epic mountain views and additional wildlife spotting.

You’ll feel like you’ve arrived on another planet when you step foot inside White Sands National Park in Alamogordo, NM. Leashed dogs are permitted to explore the world’s largest gypsum sand dune field, which began forming over 280 million years ago. Take a stroll with Fido along the Interdune Boardwalk, a raised pathway that keeps paws out of the sand while providing shade shelters and offering stunning views of glistening white sand dunes. More adventurous hounds will enjoy a hike on the five-mile Alkali-Flat Trail, just be sure to avoid hiking in the heat of the day and take plenty of water. Of course, your pup can’t visit White Sands without trying his paw at sand sledding. Rent or purchase a saucer from the gift shop, or bring your own, and find the perfect dune where you and your pup can carve out a path. Wax for the saucers can also be purchased onsite if Fido feels the need for speed.

Clean off those sandy paws and rest up at nearby Quality Inn & Suites Alamogordo. Then explore more epic landscapes at nearby Lincoln National Forest.

Most easily accessible by air, Wrangell St. Elias National Park and Preserve in Alaska may be challenging to get to, but well worth the visit with Fido. Not only is Wrangell St. Elias America’s largest national park, but it also contains some of the last areas of untouched wilderness in the U.S. Adventurous canines can trek along all trails in the park and are permitted in the backcountry as long as they’re leashed. Spot wildlife, marvel at glaciers and admire breathtaking views of the Wrangell Mountains when you explore with your pup on land or take to the waters with a sea kayak and view some of the more than 3,100 glaciers that make up the park, up close.

For an unusual overnight adventure with Fido you won’t soon forget, spend the night in one of the rustic public-use cabins scattered throughout the park. Visitors who prefer running water and plumbing can opt for a stay in the nearby Aspen Haven Cabin instead.
