This National Park is located in the very north-east of Argentina in the province of Misiones which lies right on the border with Brazil. The centre-piece is the series of spectacular waterfalls. These must be seen though in peak times the approaches and board-walk can be crowded with visitors. To see the rich diversity of wildlife, especially birds and butterflies, one should head off to other parts of the park. Parts of the sub-tropical Parana rainforest, often with bamboo, bromelias and ferns, are fairly easy to work via well-marked trails. Mammals include giant river otter, tapir, ant-eaters, aguti, white-faced capuchin monkeys and, though rare and hard to find, jaguar.
Before joining any wildlife watching or birding tour, wherever in the world, try to establish if the travel company you are considering booking with operates in an environmentally friendly, responsible manner.
