A trip to Puerto Iguazu on the Argentine border with Brazil and Paraguay gives you the chance to see two huge spectacles. One natural and one man made.

The Iguasu falls is one of the most spectacular natural features on the planet. You will be spellbound by this series of 275 seperate falls along 2.7 miles of the river. Most of the falls are within Argentina but there is access in Brazil and Paraguay too. You are able to walk quite close to the falls on fenced walkways and at some points can be surrounded by 260 degrees of waterfalls, wet with spray. You can also take a motor boat ride and pass under the falls, not for the faint hearted!

Itaipu Binacional is a company that runs the largest operational hydroelectric power plant in the world. It is an engineering undertaking run jointly by Brazil and Paraguay at the Paraná River on the border between the two countries, 15 km north of the Friendship Bridge. The project ranges from Foz do Iguaçu, in Brazil, and Ciudad del Este in Paraguay in the south, to Guaíra and Salto del Guairá in the north. The generation capacity of the plant is 14 GW, with 20 generating units of 700 MW each. In the year 2000 it achieved its generating record of 93.4 billion kilowatt-hours (kWh), which supplied 93% of the energy consumed by Paraguay and 20% of that consumed by Brazil as mesaured in 2005.
