The list of activities in Buenos Aires is endless! There are lots of tours in Buenos Aires to choose from!
The best way to know Buenos Aires is to join an
organized city tour, but there are lots of different ways to explore the city. You can book a Bike Tour, get on a bus city tour, join a walking tour, even hire an heli tour, or just get a private car and tour guide. It depends on your budget and personal preferences.

Another place you should visit while staying in Buenos Aires, is Tigre Delta. This is a beatufil are located a the north of the city. There are several tours in Buenos Aires that visit this spot. Again, you can choose from different ways of doing so. You can go by train, join a bike tour, get on a bus tour, etc. My recommendation is to take the Boat Tour that departs from Puerto Madero in Buenos Aires, and returns by train.
