How to Get to Key Largo from Miami Without a Car

Plenty of Miami visitors never rent a car — and the good news is Key Largo is the one Florida Key you can comfortably do without one. It's 60 miles from downtown, one highway the whole way, and small enough on arrival that rideshares cover the gaps. Here are the realistic options, best first.

Option 1: The day-trip bus (easiest)

The Key Largo day trip from Bayside Marketplace is built for exactly this. An air-conditioned bus leaves Downtown Miami in the morning, narrates the 90-minute ride down, drops you at the heart of the island, and departs again at 7:30 PM — about 11 hours of free time, no logistics to solve. From $29.99 for transportation only, it's usually cheaper than a same-day rental car plus gas and parking, and you can pre-book reef activities so the timing all lines up. Staying in the Sunny Isles Beach area? There's a departure with pickup there too.

Option 2: Rideshare (flexible, pricier)

Uber and Lyft both run Miami → Key Largo; expect a meaningful fare each way depending on time and demand. The catch is the return: driver availability on the island is thinner than in Miami, so build in patience for the ride home, especially after sunset. Rideshare makes the most sense for small groups splitting the fare, or for one leg combined with a cheaper option the other way.

Option 3: The Keys shuttle services

Several shuttle companies run scheduled vans between Miami (including the airport) and the Keys, stopping in Key Largo on the way to Key West. They're reliable and reasonably priced, but schedules are built around Key West, so your usable hours in Key Largo can be awkward. Worth checking if the tour bus dates don't fit yours.

Option 4: Public transit (cheapest, slowest)

Miami-Dade Transit's Route 301 (the Dade-Monroe Express) connects Florida City to Marathon with Key Largo stops, and county buses get you from Miami to Florida City. It works, it costs pocket change, and it takes the better part of forever with transfers. For the determined budget traveler only.

Getting around Key Largo once you're there

The island is long and thin with everything strung along US-1, addressed by Mile Marker. The walkable cluster around MM 100 covers the marina (home of the African Queen), restaurants and tiki bars; Pennekamp park sits at MM 102.5, a five-minute rideshare away. Uber and Lyft both operate on the island for short hops. Most reef trips, including the snorkeling adventure, leave from docks within a few minutes of the drop-off point.

The verdict

For a first visit, the day-trip bus wins on every axis that matters: cost, simplicity, and hours actually spent on the island. Save rideshare for the evening you decide the tiki docks deserve one more hour than the schedule allowed.
