The
Iguazu Falls consists of two national parks, one in Foz de Iguazu (Brazil) and the other one in Puerto Iguazu (Argentina). The curious thing is that although one only sees the falls as the main attraction, the park has a size of 252,982 hectares (67,720 on the Argentine side and 185,262 on the Brazilian side).
These falls in Argentina and Brazil managed to attract so much attention that almost at the same time they were declared National Parks (1934 in Argentina and 1939 in Brazil). And after some years and millions of visitors fascinated by the landscape and the sound of this natural attraction,
UNESCO declared them as World Heritage Site in 1984, and reaffirmed as Exceptional Universal Value (their cultural and nature it’s so important that it’s conservation should be of worldwide interest) in 2013.
