Iguazu falls offered a lot more than just a view of the falls. The park is very well developed for tourism. From Puerto Iguazu hop on a bus or hire a driver to get to the park 60 km away. From the park entry where you pay admission fees (AR$ 120 for foreigners) you will have a couple of options. There are several different view points Garganta del Diablo gives the view of the terrifying beauty of the fall from the top. It is the most popular and time consuming route which you would prefer to take the train in the park (free with admission). To take the train go for a short walk through the forest to take the train leaving from Cataratas station. At the top the walk under heat can be a little hard so bring lots of water. There are also Paseo Superior (upper trail) and Paseo Inferior (lower trail). If you been to the Garganta del Diablo I would suggest Paseo Inferior to have the view from the bottom of the falls. It is also the passage that leads to the boat rides right under the falls (Nautical Adventure - AR$ 150) and the hop to Isla San Martin. The park can take up the entire day. Bring lots of water.
