Argentina's Iguazu Falls spill over the border between Argentina and Brazil in a mighty display of nature at its most dramatic.

Iguazu is probably the most impressive of the world's great cascades and is an absolute 'must-do' on any tour of Argentina.

Iguazu Falls is located in a lush rainforest setting reached by flight from Buenos Aires and is very well set-up for visitors, with a good choice of hotels and well-organised excursions, including thrilling boat trips close to the base of the falls.

We highly recommend visiting the Iguazú Falls from both sides, the Argentinean side and the Brazilian side - with the bonus of being able to 'tick off' Brazil on your list of countries visited.
