Getting There & Away
Parque Nacional Iguazú is 20km southeast of Puerto Iguazú. From Puerto Iguazú’s bus terminal, buses leave every 20 minutes for the park (AR$75, 40 minutes) between 7:20am and 7:20pm, with return trips between 7:50am and 8pm. Three additional late-night return services run when full-moon tours operate. The buses make flag stops along the road.
A taxi from town to the park entrance is AR$300 (AR$550 return).
The park complex ends at a train station, from which a train runs every half-hour to the Cataratas train station, where the waterfall walks begin, and to the Garganta del Diablo. Overcrowding is a serious problem in peak periods and you may have to wait a long while for a spot. Seek out a printed return ticket as soon as you arrive. You may prefer to walk: it’s only 650m along the Sendero Verde path to the Cataratas station, and a further 2.3km to the Garganta, and you may well see capuchin monkeys along the way.
To see all the falls involves quite a lot of walking although you'll have many breaks as you gawk at individual cascades, and there are not many strenuous climbs.
Most of the trails are at least 90% wheelchair/pusher accessible; while there are some stairs in parts it's possible to reach all the viewpoints by navigating some of the trails in reverse or using dedicated special access paths.
