Rio Metro. The subway is the fastest public transport in Rio. There are three metro lines: Line 1, which connects the south with the north; Line 2, which connects Pavuna with the center; And Line 4, which connects the southern zone with Barra da Tijuca. In addition, the Rio subway has the ability to integrate with bus, GRT and train.

The metro runs from Monday to Saturday from 5:00 am to 12:00 am, and on Sundays and public holidays from 7:00 am to 11:00 pm. The ticket costs BRL 4.30 one way, and you can get tickets with the RioCard card top-up, which allows you to accumulate credit, or you can buy one ticket at the station.
