For the second part of our trip we spent three nights on the Argentinian border with Brazil and Uruguay at Iguazu Falls. It was definitely one of the most stunning and overwhelmingly beautiful things I have ever seen. It took quite a lot of effort to get there between flights, cabs, waiting in long lines, etc. but by the time we reached the falls we were both saying how worth it we felt the trip was. The area is considered jungle and we saw monkeys, iguanas, coatis, and tons of gorgeous butterflies and birds. We stayed at a fabulous hotel with some of the coolest swimming pools we've ever seen and monkeys just off the deck of our room.
