I am flying from Brazil to Miami Int. Airport and am looking for the cheapest way to get to West Palm Beach from there. I have been checking car rental rates, but they seem a little expensive to me ($80/day). I heard there is a train that does this itinerary. Does anyone have more info on this train option?

Tri-Rail does a route throught the three counties. Check the website:

I used to live in Miami, but work in Palm Beach and took the tri-rail. Easy and cheap.

Be advised that TRI rail station is outside the Miami airport, right next door to HERTZ Rental car . If money is an issue and you decide to ride TRI Rail, get Hertz' shuttle bus, like if you were going to rent a car, once there just walk out and to your right will be the train station.

Miguel,

Thank you for the tip. Do you know other ways to get to the TRI from Miami Airport? Is there a special bus?
