The delta area of Tigre was a big surprise for us. It was such a cute area with an amazing lifestyle that we didn't know existed. No roads, just a mess of finger like rivers with boat buses to transport people - and of course a lot of people with their own boats. It was such a peaceful and interesting place! We took the train from Buenos Aires to Tigre, then a boat bus up the delta to Tres Bocas and had a little walk around and coffee. It was a super fun day trip!
