Sneak away from mainland Rhode Island for a day or two and visit Block Island, a featured destination in our book, Ruff Guide to the United States. Hop on the Block Island Ferry for a 55-minute ride from Point Judith in Narragansett to this scenic destination. Dogs float free of charge. After docking, head to the Mohegan Bluffs, a strip of secluded beach sandwiched between impressive clay cliffs and the Atlantic Ocean. You can make the 4-mile round trip by foot, or rent a bike and trailer from Beach Rose Bicycles. If you want to get there quickly, hail a taxi (both McAloon’s Taxi and Block Island Taxi and Tours are dog friendly). After enjoying your time at the beach, check out the Southeast Lighthouse before taking a leisurely walk back to Old Harbor, or head in the opposite direction to complete a 13-mile bike ride around the island.

If one day isn't enough on Block Island, check into The Blue Dory Inn for the night. Nestled on pristine Crescent Beach, it offers proximity to the ferry, charming Victorian-style guest rooms, and fresh-baked cookies each day. Pet-friendly accommodations feature porches with stunning ocean views.

Alabama's Dauphin Island offers visitors on two legs and four an exciting Gulf Coast getaway.

With so much to see and do, you might want to extend your stay. Dauphin Island Harbor House, a favorite among four-legged beach bums, is a fine choice of pet-friendly lodgings. Humans will love the complimentary full Southern-style breakfast each morning, and your water-loving pooch will appreciate the proximity to miles of dog-friendly beaches.

The resort also offers access to more than 20 miles of pathways, including the North Loop Trail and the Ocean View Trail. In the evening, get cozy around the fire pit with your canine as the sun sets over the water.

Hop aboard a Washington State Ferry in Anacortes for a trip to San Juan Island. When you arrive at Friday Harbor, ditch the car in favor of a ‘Scoot Coupe’ from Susie’s Mopeds, which will serve as your mode of transportation for the day. Scoot two miles to Jackson Beach, where your pup can run free in the sand. Continue to San Juan Island National Historical Park to learn about the history of the island and the Pig War. Make a pit stop at Pelindaba Lavender Farm to let Fido roam the fragrant fields and try a lavender-flavored dog biscuit. Then, check out Lime Kiln Point State Park, where whales are commonly spotted between May and September. When you complete your loop around the island, refuel with a hearty sandwich on Market Chef’s patio. There’ll be enough to share with your hungry hound!

If you want to keep exploring San Juan Island with your dog, spend the night at Earthbox Inn & Spa. Located just four blocks from the Friday Harbor Ferry Landing, the dog-friendly property offers clean, modern accommodations and a dog run. Enjoy complimentary use of the hotel’s beach cruiser bikes to explore the charming island, schedule a hot beach stone massage, or relax in the heated indoor pool.

Escape to Blennerhassett Island State Park in Parkersburg, West Virginia, for a special day out with your pup. Located in the middle of the Ohio River on the border between West Virginia and Ohio, the park is home to numerous trails, manicured grounds and a reconstructed Palladian mansion that offers visitors a historical glimpse at colonial plantation life. To reach the island, climb aboard the Island Belle sternwheeler for a short 20-minute riverboat journey. Upon arrival, stretch Fido’s legs on a self-guided walking tour. Along the way, you’ll see volunteers in period costume and horse-drawn covered wagons carting visitors around. The park is open from early May through mid-November, with ferry service offered Tuesday through Sunday. Afterward, explore charming downtown Parkersburg and stop for dinner at the dog-friendly Parkersburg Brewing Co.

Located just a few blocks from the ferry, The Blennerhassett Hotel is the “pawfect” pet-friendly hotel if you decide to spend the night. Fido will be welcomed at this Gaslight-era hotel with complimentary dog treats, food bowls to use during his stay, and waste bags.

Off the coast of North Carolina, Bald Head Island is a pretty destination with plenty to see and do. Start your adventure at Deep Point Marina - Bald Head Island Ferry in Southport, where a scheduled ferry service will take you and your pooch on a 20-minute trip to the island. Upon arrival, take a short walk to the pet-friendly Cary Cart Company and rent a golf cart, which will serve as your mode of transportation on this car-free island. If you prefer to pedal instead, daily and weekly bike rentals (with bike trailers or baskets for Fido) are available from Riverside Adventure Company. After securing your wheels, cruise the cart path and explore 14 miles of sandy beaches, hit the surf for some fun on the water, and take a hike with your canine companion on one of the lovely trails running through this island community.

Extend your visit to Bald Head Island by renting a cozy dog-friendly vacation home. Our Tern is a beautifully decorated rental that sleeps eight, has a fenced-in backyard for Fido, and a large screened porch with a gas grill.

Located on Lake Huron, Michigan's Mackinac Island is filled with fun activities you can enjoy with your pup, and nearly all of the historic sites and buildings allow leashed pets. Your adventure begins with a 15-minute ride aboard Shepler’s Ferry. Motorized vehicles are not allowed on the island, so you’ll have to get around on two (or four) legs. With a circumference of only eight miles, it is possible to explore the entire island. However, if you’d prefer not to “hoof it,” you can pay a horse to do it for you! Mackinac Island Carriage Tours offers fully narrated two-hour tours with stops at Arch Rock, Fort Mackinac, and several other points of interest. Lapdogs are free, and larger dogs ride for the price of a child’s ticket.

Mackinac Island is worth a longer stay. Spend the night at Mission Point Resort and book the hotel’s “Pooch at the Point” package, which includes accommodation in the resort’s historic Straits Lodge, roundtrip transfers on Shepler’s Ferry, an assortment of welcome amenities for pups, and a daily food and beverage credit at the onsite restaurants.

Get away from the stress of everyday life with your pooch on a day trip to Keewaydin Island in southwest Florida. Located along the coast between Naples and Marco Island, this eight-mile-long barrier island boasts sugar sand beaches and some of the finest shelling in the Sunshine State. The area is accessible only by boat, but if you don’t have one of your own, you can rent a powerboat from the marina at Naples Bay Resort & Marina or from Captain Joey D. Charters and Boat Rentals located at Hyatt House Naples 5th Avenue. Because Keewaydin Island is a conservation area, dogs must remain leashed during your time on the beach. If your sea dog wants some off-leash fun, return to the mainland and head north to Bonita Beach Dog Park, located on the south end of Lovers Key in Fort Myers Beach.

After a full day of island fun, kick back and relax at the Naples Bay Resort & Marina where Fido will be greeted with a treat and have designated pet areas just for him!
