Metromover is a free, driverless, elevated railway looping through downtown Miami, Brickell and the Omni district, and it is the single most useful thing a visitor to central Miami can learn about. It costs nothing. There is no ticket, no tap, no gate — you go up the escalator and get on.
It is also, accidentally, a very good ride. The guideway runs two or three storeys up, threading between office towers, over the Miami River, past the bay. The cars have no driver, which means the front window is a seat rather than a cab. Sit at the very front, going anticlockwise round the Inner Loop, and you get a slow, free, air-conditioned tour of downtown at the exact height where the architecture makes sense.
The system is about 4.4 miles across 21 stations, arranged as three loops. The Inner Loop circles the downtown core. The Omni Loop runs north to the Adrienne Arsht Center and the Omni district. The Brickell Loop runs south over the river into the financial district. Understanding which loop you want is the only skill involved, and getting it wrong just means a longer, still free, ride.
It opened in 1986 as the downtown loop, gained the Brickell and Omni extensions in 1994, and shed its small flat fare in the early 2000s.
What it reaches, for a visitor: the Pérez Art Museum and Frost Science at Museum Park, Bayside Marketplace, the Freedom Tower, the Arsht Center, the Kaseya Center, the Riverwalk, Brickell City Centre, Government Center for Metrorail, and the Overtown Lyric Theatre district.
What it does not reach: Miami Beach. There is no rail link of any kind between the mainland and the beach. That is one of the defining facts of getting around this city, and nobody tells you until you are standing on a platform with a hotel booking in South Beach.
