Some road trips require leaving the dog at home with a sitter and a guilty conscience. Not this one. The 113-mile Overseas Highway through the Florida Keys has been ranked the world's most dog-friendly driving route by AutoTrader, and the numbers back it up: 43 service stations, 19 outdoor areas and seven dedicated dog parks along the way — roughly three dog stops for every five miles of road.

The highway itself is reason enough to drive it. It hops island to island across open ocean, so you're rarely out of sight of water. Flying in is simple too — start the route in Key Largo, about an hour south of Miami International Airport, or pick it up just outside Key West if you land at the smaller Key West airport.

Beyond walks and roadside breaks, dogs in the Keys get unusually full itineraries. BringFido notes pups can join paddle trips, ride tiki boats and even walk through an aquarium along the route. For a proper beach stop, pull off in Marathon: Sombrero Beach, a six-minute detour off the highway, earns a top rating for white sand, calm wading water and dog shower stations. Marathon's own Dog Park sits directly off the road if you're watching the clock. At the southern end, Higgs Beach in Key West pairs sand time with a fenced dog park.

Overnight options are refreshingly easy. La Siesta Resort and Villas in Islamorada offers colourful beachfront villas where dogs are welcome — with kayaks, a private beach and even butler service on offer. Alternatives include Coral Lagoon Resort in Marathon, Bayside Villas by Islander Resort in Islamorada, and Ambrosia Bed and Breakfast, a historic Key West home.

Eating with your dog is similarly straightforward. Islamorada Fish Company gets consistent praise for accommodating pups, complete with water bowls and refills. Further down the chain at Ramrod Key, Boondocks Grille and Draft House reportedly goes a step further with an actual dog menu.

Who is this for? Anyone who considers the dog a travel companion rather than luggage. The Overseas Highway suits a slow, multi-day trip — drive a stretch, stop at a beach, eat waterside, sleep in a villa, repeat. It works equally well as a long weekend from Miami or a one-way run ending in Key West, and the density of pet-friendly infrastructure means you're never scrambling for a plan B when your dog needs a break. Pack the leash, book early for high season, and let the pup enjoy the salty breeze out the window.
