An easy (and cheap) way to get out of town for the day is by taking the Tren de la Costa from Buenos Aires to Tigre (or one of the many relaxing stops along the way).
This small train hugs the river’s coastline and features antique stations, markets, hip open-air restaurants, and outdoor activities like kayaking and windsurfing.
Stations/Stops of Note:
Maipu is the first station in the city in the suburb of Olivos, one terminal for the Tren de las Costa.
