There are plenty of good hotels in Iguassu Falls, both in the Brazilian side and in the Argentinean. The final choice depends a lot upon what you want.
In the Brazilian side, most of the hotels are located near the road that surrounds the Iguassu river, between the falls and the city of Foz do Iguacu, or in the very city. Distances from the hotels to the Falls are short: 15-20 Kms (miles) at most. See: Map of Iguassu Falls region. This main Brazilian road is signalled with the number 13, on the map.
In the Argentinean side, most of the hotels are also bordering the park and not far from the river, between the city of Puerto Igussu (or in this city) and the Falls. See: Map of Iguassu Falls region. This main Argentinean road is signalled with the number 14, on the map.
- Easter as well as January and February are high season periods. Hotel prices in these periods are high, and reservations should be done early enough. If you don't like crowded places and if you bet in low hotel prices, these are not the best months to visit the Iguassu Falls.
- Though you can look for hotels in the Brazilian or in the Argentinean side of the Iguassu Falls, the Brazilian offer is much wider. Avoid accommodation in Paraguay: Ciudad del Est is too unsafe.
- You can stay just one night, or even arrive at the morning and depart in the late afternoon, for a quick visit. But that might be very tiring and you will just get a big picture of the place. The region offers other possibilities, which require at least one night in the hotel.
