Key West Travel Guide
Three Days in Key West
The itinerary that books the boat days first — a history morning and Mallory sunset, a full day at Dry Tortugas, a reef snorkel and Fort Zach beach day, and how to adjust for kids, cruise ships, and bad weather.
Three days on Key West is enough to do the island properly if the boat days are booked first and the walking happens in the cool hours. The rhythm is simple: mornings for history, middays on or in the water, and every evening ending with the sun going down over the Gulf.
Before you go: book the water. The Dry Tortugas ferry or seaplane is the one booking that can make or break the trip — reserve it the moment your dates are fixed, ideally for day two so a weather cancellation leaves you a fallback day. Book the reef snorkel trip for a morning on day three. If you want a sunset sail, book it for any evening except the first, which belongs to Mallory Square. Everything else can wait until you arrive.
Day one — orientation, Hemingway, and the first sunset. Start early with the Conch Train's hour-long narrated loop from the Front Street depot; it gives you the island's story and geography before the heat builds. Hop off and walk to the Hemingway Home for the guided tour and the six-toed cats, then cross Whitehead Street and climb the lighthouse's 88 steps for the view down into Hemingway's garden. Lunch on a porch nearby — Cuban sandwiches, conch fritters, or fish tacos. In the afternoon, walk Duval Street south to the Atlantic, stopping at the Butterfly Conservatory and the Southernmost Point replica buoy at the foot of the street, then rest at the hotel pool. Late afternoon, head to Mallory Square: an hour in the Shipwreck Treasure Museum first, climbing its 65-foot lookout tower, then out onto the square as the Sunset Celebration builds. Bring small bills for the performers, claim a waterfront spot, and applaud with everyone else. Dinner, then the Duval Crawl as long as you like.
Day two — Dry Tortugas. An early start: the ferry boards at the Key West ferry terminal on the Historic Seaport in the early morning, with breakfast on board for the crossing of a little over two hours. On Garden Key, take the ranger or crew fort tour of Fort Jefferson first, then snorkel the moat wall, where coral and tropical fish crowd the old brick, and save time to stand on the fort's top tier looking out over seventy miles of nothing but water. Lunch is served on the boat. You are back in Key West in the late afternoon — tired, sunburned if careless, and happy. Shower, and if you have energy, catch sunset from the Sunset Pier at Ocean Key or the Historic Seaport's waterfront bars, then dinner close to the hotel. If the weather cancels the ferry, swap days two and three.
Day three — reef, beach, and the President. Morning reef snorkel trip from the harbor: three hours on a catamaran with two stops on the coral reef, gear and instruction included. After lunch, walk or bike to the Truman Annex for the hour-long docent tour of the Truman Little White House, then continue through the Annex gates to Fort Zachary Taylor Historic State Park. Walk the Civil War fort's gun rooms, then swim and snorkel off the park's rocky beach, the best on the island, and stay until sundown — the park's western shore is the locals' sunset spot, calmer than Mallory. Final dinner somewhere memorable, and a last nightcap at a live-music bar.
Pacing the heat. Even in winter the midday sun is strong, and from May through October it is fierce. The itinerary above is built around that: the walking sights are front-loaded into the mornings, the middle of each day is spent on a boat or in the water, and the evenings are for strolling once the heat breaks. Carry water everywhere, wear a hat, and reapply sunscreen after every swim. Bicycles make the longer hops — Old Town to Fort Zach, the Historic Seaport to the Southernmost Point — quick and breezy, and nearly every hotel can arrange one. If you only have energy for one evening out, make it day one or day three; the Dry Tortugas day is long, and most people are asleep early.
Where to eat along the way. Breakfast is a Key West ritual worth building around: a Cuban coffee and pressed toast from a walk-up window on day one, an early breakfast before the ferry on day two (the boat serves one too), and a long, lazy breakfast in a garden courtyard on day three before the reef trip. Lunches are best casual — fish sandwiches, conch fritters, and key lime pie by the slice. Book one special dinner in advance for the final night, ideally somewhere with a garden or a harbor view; everything else can be decided on the walk.
With kids. Swap the Duval Crawl for an early dinner and the Sunset Celebration's animal acts and jugglers, which are pitched at children anyway. The Butterfly Conservatory, the Shipwreck Museum's actors and tower, the Conch Train, and Fort Zach's picnic grove and cannons are all strong family picks; the Key West Aquarium next to Mallory Square is a good addition for young children. Dry Tortugas works brilliantly for kids who swim, less so for toddlers.
With a fourth day. Drive an hour up the Overseas Highway to Bahia Honda State Park for the Keys' best sand beach and the old Flagler railroad bridge, adding the Old Seven Mile Bridge walk and a drive back into the sunset. Or keep it local: a sunset sail, the Audubon House gardens, the Key West Cemetery, and a long lunch.
When the weather turns. Winter cold fronts can bring a couple of windy days that cancel boat trips. Have indoor options ready — the Hemingway Home, Truman Little White House, Shipwreck Museum, Butterfly Conservatory, and the island's galleries — and keep your boat bookings flexible. Summer storms usually blow through in an hour; wait them out on a covered porch.
Cruise-ship days. If ships are in port, do the big sights before ten or after four. The middle of the day is for the water and the pool.
