The route at a glance
From Miami, take the Turnpike south to Florida City, then US-1 becomes the Overseas Highway all the way to Key West. It's a single scenic road — hard to get lost, easy to fall in love with. The Turnpike leg is a cashless toll road, so a SunPass-ready car keeps you moving.
Best stops along the way
Key Largo
The "Diving Capital of the World." John Pennekamp Coral Reef State Park for snorkeling and glass-bottom boats.
Islamorada
The "Sportfishing Capital." Great lunch stop — fresh seafood, Robbie's tarpon feeding, art galleries.
Marathon & Seven Mile Bridge
The Turtle Hospital, then the iconic Seven Mile Bridge — the drive's showstopper.
Bahia Honda State Park
Arguably the Keys' best beach — a perfect leg-stretch and swim before the final push.
Key West
Duval Street, the Southernmost Point buoy, Mallory Square sunset, Hemingway's house. Mile marker zero.

Tips for the drive
- Leave early (by 8–9am) to beat weekend traffic on US-1 and enjoy the stops.
- One road in, one road out — build in buffer time; a crash can back up US-1.
- Fuel & snacks in Florida City or Key Largo — prices climb further down the Keys.
- Best car: a convertible makes the bridges unforgettable.
