This elevated, electric monorail is hardly big enough to serve the mass-transit needs of the city, and has become something of a tourist attraction. Whatever its virtues as a commuting tool, the Metromover is a really great (and free!) way to see central Miami from a height (which helps, given the skyscraper-canyon nature of downtown). Because it’s gratis, Metromover has a reputation as a hangout for the homeless, but commuters use it as well.
