With an average height of 72m / 236 ft across a river's edge 2.7kms /1.6 miles 
wide and with at least three names they are greater than Niagara. In some dry 
seasons there are as many as three hundred separate falls and in flood times there 
are as few as three. They lie within two national parks in subtropical forest 
filled with countless birds and butterflies. Many mammals including jaguars, giant 
otters, coatis and bush dogs live in places off the beaten track. The falls are 
a UNESCO World Heritage Site and and one of South America's greatest natural spectacles.

 |   These 
remarkable falls on the border of Argentina and Brasil approximately 550 km / 
340 miles inland from the Atlantic ocean and named after the river they dominate. 
The name varies according to the various local languages though the same suffix 
or ending azú, assú or açu is used. It is derived 
from Tupi Guarani the original language family of the area and means 'big'. The 
falls comprise roughly 300 falls. Below the falls the river races through a narrow 
gorge before entering the River Parana the major tributary of the River Plate. 
The falls were were discovered early in 1542 by a Spanish commander Álvar 
Núñez Cabeza de Vaca and were declared a World Heritage Site in 
1984 and 1986 The falls lie within the boundaries of two National Parks - one 
Argentinian and the other Brasilian.   |

 |   The 
river Parana running north to south is one of the world's greatest rivers. It 
rises in Brasil and with a major tributary the Paranaiba has a length of about 
3998 kms / 2484 miles. The Parana carries a a huge volume of water and is crossed 
by a bridge between two cities in the top left. Ciudad del Este in Paraguay and 
Foz de Iguaçú in Brasil, literally meaning ' mouth of the Iguaçú 
'.  The 
massive Itaipú dam straddles the Parana jbetween Paraguay and Brasil ust 
outside the top left hand corner of the map  |    | The 
river entering from the east in the top right is the Iguazú or Iguaçú 
as it is known in Brasil. It rises close to the Brasilian city of Curitiba within 
approximately 50kms / 31 miles of the Atlantic ocean and has a total length of 
approximately 1198kms / 745 miles most of which is in Brasil. The falls are in 
the green shaded and forested area on the right where the river narrows. A bridge 
crosses the Iguazú at the Argentinian town of Puerto Iguazú close 
to the confluence. |     |

 |   THE 
DISCOVERY By 1542 Spanish and Portuguese explorers were getting to 
know their way around South America. Ten years earlier over on the Pacific coast 
Francisco Pizarro had found his way in to the Inca Empire. On the Atlantic coast 
the mouth of the Amazon was discovered by a Spaniard in January 1500 and soon 
Portuguese traders began small settlements for collecting a richly coloured 'brazil 
wood' from the forests.The name comes from the Latin 'brasile' meaning 
red. Meanwhile the River Plate from the Spanish word plata meaning silver 
attracted explorers trying to find a way to a land they believed was rich with 
the precious metal. One expedition left Seville in Spain in 1535 and headed for 
the River Plate. The adventurers set up a base near the site of present day Buenos 
Aires and exploratory groups were despatched inland. One commanded by a Spaniard 
Juan de Salazar went up the river Parana and then to the River Paraguay where 
his men built a stockade they called Asunción.  
Back at base the leader of the main group fell ill and decided to return to Spain. 
He died at sea and when news of his death and the isolated garrison at Asunción 
reached Spain a relief expedition was sent out. The commander Álvar Núñez 
Cabeza de Vaca was a travel-hardened Spaniard from the city of Jerez de la Frontera 
in southwestern Spain. He had already made his name by exploring Florida, parts 
of Texas and some of Mexico between 1528 / 36. Álvar Núñez 
eached Santa Catalina Island [now Santa Catarina] on the coast of Brasil late 
in 1541 and decided to strike boldly inland at roughly the right latitude to reach 
Asunción overland. In late 1541 Álvar Núñez set out 
with two hundred and fifty men and twenty six horses from close to where the city 
of Florianopolis stands today.   
expedition headed into an incredible wilderness of low mountains - the Serra 
do Mar, dense forests and huge rivers. The Spaniards had no idea of the kind 
of reception they would meet from the indigenous,Tupi Guarini native population, 
Reports from friendly people along the way were good and they found the headwaters 
of the Yguazú river and followed it westward downstream. Some of the explorers 
used canoes and others travelled by land. In January 1542 the reached the falls.....' 
The current of the Yguazú was so that the canoes were carried furiously 
down river, for near this spot there is a considerable fall and the noise made 
by the water leaping down some high rocks into a chasm may be heard a great distance 
off and the spray rises two spears high and more over the fall....

park was created in 1934 and covers 55,000 hectares. In 1984 it was named by UNESCO 
as a World Heritage Site. The park entrance is xx kms by road from Puerto Iguazú. 
From the Visitor Centre at the entrance to the park a mini-railway takes a route 
into the forest with stops at a Cataratas station for many of the falls and walks 
beside the river. The train continues to the Devil's Throat station where another 
walk at a higher level leads above one of the most spectacular falls |   |

From a visitor centre at the entrance to the park luxury omnibuses make the journey 
to the forested edge of the falls. An observation tower stands beside the largest 
fall and below and at the water's edge walkways extend over the river to even 
more falls. |   |

side is best? Both can be visited easily in one day and both are wonderful. 
To see much of the wildlife a longer stay is needed with arrangements to trek 
deeper into the parks. | 
   
   
  
 Tiny 
fungi grow on fallen branches above the river. This is a tropical wet forest and 
the rainfall averages 1600mm per year. It is a forest of several layers including 
emergent canopies. The humid air from rain and spray from the falls helps the 
growth of many plants, especially bromeliads, mosses and ferns   |
