Although there was a record number of travellers who visited the waterfalls over the course of the year, I was surprised to find that Puerto Iguazu has managed to remain a tranquil spot. As soon as you are out of the centre of town you are surrounded by sub-tropical vegetation. There are palm trees in the gardens and the untarmacked roads become bright red earth. Totally beautiful colour contrasts.
It's really easy to get to the falls. Buses leave from the central station at different times of the day for the Argentine or Brazilian sides of the falls. They also stop at the hotels, so check with your reception. It's the cheapest solution.
When you are creating the itinerary of your trip to Argentina, you should remember that you can fly directly to Puerto Iguazu from Buenos Aires or Salta.
Puerto Iguazu has a gentle atmosphere. You feel good there, relaxed, because the town is surrounded by the jungle! It's a change from Buenos Aires. You can either get there by bus (check the distances, Puerto Iguazu is in the extreme north) or by plane. Then you have a good trot through the jungle, in a vehicle obviously, which gives you a foretaste of the magnificent scenery around the Iguazu waterfall. You might even see some toucans on the road!
In the centre of town, around the bus station, are the restaurants and tourist shops. If you've got the time you can easily cross over the Brazilian frontier to see the waterfalls from the other side. There are hotels and youth hostels everywhere. We had no problem finding a room at a moment's notice. Puerto Iguazu really only exists because of tourism.
