Perhaps the greatest waterfalls in the world is Iguazu Falls (Spanish in Argentina), or Iguacu Falls (Portuguese in Brazil). The Guarani indigenous group call it Iguazu, meaning great river. The Rio Iguazu (the Argentinian name) forms the border of Argentina and Brazil. The falls is not the tallest, the most voluminous, or the most of anything else. It is just so overwhelming in its entirety. People generally take two days to visit it, as it is so spread out. It is nearly two miles long when one adds up all its courses and channels. It has 275 separate falls, the tallest being 270 feet high. Many walkways allow visitors to walk above the river, especially on the Argentinian side.
This was my second visit to the falls, the first being in February 2003 following my trip to Antarctica. The water level was lower this time, but the falls were still spectacular.
