Also in the area are a number of fresh water pools and small cataracts. There are reports of a proposed train to the falls on the Argentine side, so people won't have to drive up to them, though nothing is running yet. Buses are the easiest way to get to the falls from each of the countries. The best time of year to visit the falls is around October and November, or March and April. Rainfall is abundant year-round, so come prepared to get a bit wet.
Summer is the most humid and rainy, though it is still possible to visit.
But you might have a problem with mosquitoes and bugs. Where to Stay Each country bordering the falls offers accommodations close by. The Argentine side is building up accommodations and tourist facilities. They are fabulous. Currently there are large hotels such as the Sheraton International Iguazu Hotel, near the falls, as well as places to stay in the nearby town of Puerto Iguazu.
