Buenos Aires is one of my favourite cities in the world. I lived there for 7mths and even ended up buying an apartment there (not recommended unless you want to enter a world of stress!!).
Buenos Aires may not be the most obvious place to get off the beaten track, but there are actually plenty of opportunities if you want to escape the city and venture into the countryside or simply get away from the other tourists.
Whether you want to escape into a wild delta, walk through a vast nature reserve, or discover some of the less-visited parts of the city, there is plenty to keep you busy.
