Miami and Key Largo sit about 79 km (49 mi) apart in a straight line, with Key Largo to the south. It is leg 1 of 2 on our Florida Keys Adventure itinerary, a 4-day trip. Here is how long it takes by car, what to see on the way and where it fits in a real itinerary.


Road distance is estimated as 1.2–1.4× the straight line; drive time assumes average speeds of 50–80 km/h with no stops or traffic. These are rough estimates — check a maps app for the actual route.
We don't have live routing data, so the figures below are labelled estimates built from the straight-line distance. Use them to plan the day, then confirm in a maps app.
Most travelers on our Florida Keys Adventure itinerary do this leg by car. We estimate 95–111 km (59–69 mi) of road and 1 h 15 min – 2 h 15 min behind the wheel, so check live traffic before you set off.
Most travelers rent a car in Miami and take the Overseas Highway all the way to Key West, enjoying the views as they go. Traffic can be slow at times, so leave extra time. Some people fly into Key West or take a shuttle for part of the trip.
