Florida Keys vs Chicago

The Florida Keys are America's most famous road trip island chain, a necklace of coral islands linked by the Overseas Highway as it hops 113 miles from Key Largo to Key West over 42 bridges and turquoise water. Starting from Miami, you can be snorkeling North America's only living coral barrier reef at John Pennekamp Coral Reef State Park within a couple of hours. Farther south, Islamorada is the sportfishing capital with tarpon feeding at the docks, Marathon has a sea turtle hospital and the soaring Seven Mile Bridge, and Bahia Honda State Park offers some of the best natural beaches in the Keys. The road ends in Key West, a colorful, easygoing town of conch houses, Hemingway's cats, and the nightly sunset celebration at Mallory Square. This plan covers the full Key Largo to Key West run in four days, then adds a day trip by ferry or seaplane to remote Dry Tortugas National Park and its giant brick fort. Navigate by the green mile markers, slow down in Key deer zones, eat plenty of fresh fish and key lime pie, and book Key West hotels early in winter.

Chicago is the American city that gave the world the skyscraper, and it still shows off its skyline better than almost anywhere. Glide along the Chicago River on an architecture cruise as guides decode Art Deco towers, glassy modern giants and the movable bridges overhead. Stroll Millennium Park to see your reflection bend in Cloud Gate, then follow the Riverwalk past cafes, kayakers and wine bars tucked below street level. Dinner means deep-dish pizza, a buttery, cheese-loaded pie that takes about 40 minutes to bake and is worth every one, though locals will also steer you toward tavern-style thin crust and an Italian beef. Evenings belong to Lake Michigan: ride a bike along the Lakefront Trail and watch the towers catch the last light at sunset. The L trains make it easy to roam without a car, from Loop landmarks to neighborhoods like Wicker Park and Lakeview. Stay longer and add the Art Institute's world-class collection, Navy Pier, a game at Wrigley Field, the lakeside Museum Campus and the free Lincoln Park Zoo. Summer brings festivals and patio season; winter brings serious cold, but also holiday markets and cozy blues clubs.
