The SUBE card pays for the Subte, buses and suburban trains across the Buenos Aires region; buy and top it up at stations and kiosks (argentina.gob.ar/sube).
Trains from Retiro and Constitución
Trenes Argentinos runs the suburban lines: the Mitre line from Retiro to Tigre for the delta, and trains from Constitución to La Plata (argentina.gob.ar/transporte/trenes-argentinos).
Across the river to Uruguay
Buquebus (buquebus.com) sails to Colonia del Sacramento and Montevideo, and Colonia Express (coloniaexpress.com) to Colonia. Take your passport and allow time for passport control at the terminal.
