The 113-mile stretch of the Overseas Highway connecting Key Largo to Key West is one of America’s most spectacular drives. But the real magic of the Florida Keys lies in stopping along the way. Each island community has its own distinct personality, from the diving capital of Key Largo to the laid-back fishing villages of the Middle Keys to the artistic energy of Key West.
Whether you’re planning a weekend escape or a week-long exploration, island hopping through the Keys rewards travelers who take their time. Here’s how to experience the best of each stop along the way.
Key Largo: Where the Keys Begin
Mile marker 100 marks the official start of your Keys adventure. Key Largo claims bragging rights as the diving capital of the world, thanks to the nearby John Pennekamp Coral Reef State Park—America’s first underwater park. Even if you’re not a certified diver, glass-bottom boat tours and snorkeling trips let you see the living coral reefs and tropical fish that make these waters famous.
Stop at the original African Queen boat (from the Humphrey Bogart film) at the marina, now a floating attraction. For a true local experience, grab conch fritters at Mrs. Mac’s Kitchen, a no-frills spot that’s been feeding locals and visitors since 1976. The breakfast is legendary, and you’ll likely share a table with someone who’s been coming here for decades.
Key Largo is also home to some of the Keys’ best sunsets over Florida Bay. Head to Sundowners restaurant at mile marker 104 for views across the water as the day ends.
Islamorada Through Marathon: The Middle Keys
Islamorada, the self-proclaimed “Village of Islands” between mile markers 90 and 74, is sportfishing central. Charter boats leave daily from Bud N’ Mary’s Marina, and even if you’re not fishing, the dock at sunset is prime people-watching. The village also hosts Theater of the Sea, Florida’s second-oldest marine mammal facility, where you can swim with dolphins or watch sea lion shows.
Don’t miss Robbie’s Marina at mile marker 77.5, where massive tarpon gather at the docks waiting to be hand-fed. It’s quirky, touristy, and absolutely worth the stop. The adjacent shops and cafés make it easy to spend an hour here.
As you continue south, stop at the Old Seven Mile Bridge viewing area near Marathon. The bridge, which once carried Henry Flagler’s railroad to Key West, now serves as a fishing pier and walking path. Marathon itself is the working-heart of the Keys—less polished than Key West, more authentic, with excellent seafood restaurants and the Turtle Hospital, where you can tour the facility and meet rescued sea turtles.
Big Pine Key and the Lower Keys
Between Marathon and Key West, the islands grow quieter and more residential. Big Pine Key is home to the National Key Deer Refuge, where you can spot the diminutive Key deer—a subspecies that stands only about two feet tall at the shoulder. Drive slowly through the refuge at dawn or dusk for your best chance of seeing them.
Bahia Honda State Park at mile marker 37 offers one of the Keys’ best natural beaches. The old Bahia Honda Rail Bridge towers overhead, and the park’s Sandspur Beach is perfect for swimming in calm, clear water. Arrive early—parking fills up by mid-morning during peak season.
Looe Key, accessible by boat from Ramrod Key, rivals Key Largo for snorkeling and diving. The reef here is pristine, and tour operators run daily trips to the underwater preserve.
Planning Your Island Hop
The beauty of Keys island hopping is that you can take as long or as little time as you want. Some travelers blast through in a day, stopping only for photos at the Seven Mile Bridge. Others spend a week, dedicating two or three days to each region.
For a solid introduction, plan three to four days: one night in Key Largo, one in Islamorada or Marathon, and one or two in Key West. This gives you time to dive or snorkel, eat fresh seafood, and experience each island’s vibe without feeling rushed.
Mile markers count down from 126 in Florida City to 0 in Key West, making navigation simple. Most hotels, restaurants, and attractions list their mile marker in their address. Gas stations become less frequent in the Lower Keys, so fill up in Marathon or Big Pine.
Visit between December and April for the best weather, but expect higher prices and more crowds. September and October bring bargains and fewer tourists, though you’ll need to watch the weather during hurricane season. Summer is hot and humid, but afternoons often bring cooling thunderstorms and the fishing is excellent.
The Overseas Highway has limited passing zones and just one lane in each direction. Don’t tailgate the car in front of you—the Keys operate on island time, and rushing only increases your stress. Pull over at scenic overlooks, let faster traffic pass, and remember that the journey is as important as the destination.
