There is a touristy train connecting the different places to visit in the park. The first station is the Central Station located at the visitors center. Then the train stops at "Cataratas Station" from where you will take the inferior and superior circuits, and the last station "Devil's Throw" from where you will walk to the main waterfall.

The train is free once you have paid the admission ticket of the park. You will not see the falls from the train, but the jungle is pretty interesting too and you will enjoy the ride.

There are clean bathrooms and  drugstores at the train  stations.
