By Plane

Miami Beach is served by two airports: Miami International Airport which is 10 miles west of Miami Beach and Ft. Lauderdale/Hollywood International Airport which is 25 to 30 miles from Miami Beach. All major domestic and international flights arrive at these two airports.

From Miami Airport, you can take the J or 150 bus. From Fort Lauderdale Airport, you can take the #1 Broward County bus to Aventura Mall for the Miami-Dade S bus.

Shared Taxi/Shuttle Service- For a cheaper ride from the airport to your destination in South Beach, you can opt to use a "shared taxi/shuttle service", which can be found outside of the baggage claim area. No need for reservations. For your trip back to the airport, you can contact the company to pick you up from your hotel and take you back at the same rates.

Public Transportation

Public transportation in South Beach, along with Downtown and Brickell, is heavily used, and is a vital part of South Beach life. Although South Beach has no direct Metrorail stations, numerous Metrobus lines (operated by Miami-Dade Transit), connect to Downtown Miami and Metrorail (i.e.: the 'S' bus line). The 'South Beach Local' or 'SBL' is one of the most heavily-used lines in Miami, and connects all major points of South Beach to other major bus lines in the city.

The Airport-Beach Express (Route 150), operated by MDT, is a direct-service bus line that connects Miami International Airport to major points in South Beach. The ride costs $2.35, and runs every 30 minutes from 6:00 a.m. to 11:00 p.m. seven days a week.

South Beach, along with a handful of other neighborhoods in Miami (such as Downtown and Brickell), is one of the areas where a car-free lifestyle is commonplace. Many South Beach residents get around by foot, bicycle, motorcycle, bus or by taxi, as the neighborhood is very urban, and pedestrian-friendly. Automobile congestion in the area is frequent, so getting around in South Beach by car can often prove more difficult than simply walking. Recently, Miami Beach has begun bicycle initiaves promoting city-wide bike parking and bike lanes, that have made bicycling much more popular for residents and tourists. The Venetian Causeway for example, is a popular bicycle commuter route that connects South Beach to Downtown.

Lincoln Road, Ocean Drive, Washington Avenue, and Collins Avenue are popular shopping, eating, and entertainment streets for pedestrians. Lincoln Road is a pedestrian-only shopping street, and Collins Avenue around 5th Street, is mostly upscale retail.

Currently, a streetcar system, named 'Baylink' is in the planning stages. Baylink would connect South Beach to Downtown at Government Center Station via the MacArthur Causeway.
