When I want to escape city life, I head to Reserva Ecológica Costanera Sur, a huge nature reserve. It’s only 3 blocks from Puerto Madero, one of the trendiest spots in Buenos Aires, but it's filled with trees and it’s a great spot for cycling by the river.
Avenida Tristán Achával Rodríguez 1550, Buenos Aires City
Open Monday-Sunday 08:00-17:00. Check website for details
