See main Iguaçu Falls article. To the north of the province of Misiones, on the border with Brazil, are the majestic Iguazú Falls: one of the Seven Natural Wonders of the World and, undoubtedly, one of the most spectacular places in Latin America. Both its location in the middle of the jungle and its enormous volume of water and numerous waterfalls make them an unforgettable place and a must-see on any trip to Argentina. The National Park was created in 1934 and declared a World Heritage Site by UNESCO in 1984. It also received the mention of Area of Importance for the Protection of Birds (AICA).
Be sure to stop by this beautiful, peaceful little garden which is full of hummingbirds. The owner has been placing feeders for wild birds for 40 years. None are in a cage. Great photo opportunities abound. There are other birds, as well, but the different types of hummingbirds that come to feed, perch and just fly around is amazing. It is a great place to sit and watch and reflect. (There are no other services inside, and advance reservations are preferred.)
