Argentina’s Travel Guide - Trekking.

Iguazú Falls - the largest waterfalls in the world - is made up of over 275 separate falls, nearly three km of the Iguazú River, and is bordered by two countries. Argentina and Brazil share this massive display of water, subtropical rain forest, and the exotic wildlife that thrives within the Iguazú National Park in the Misiones province. Without a doubt, the sight-seeing options are endless and the more time spent on foot, the more discoveries there are to be made.
Upon entering the park each visitor will receive a map that shows each and every path in the park. The regulated use of these foot trails has been essential in preserving and maintaining the thousands of acres of forest that make up Iguazú National Park. To cover them all, two full days of trekking through the forest is recommended. …

Glad you liked our trekking guide! And good choice on Iguazu, it really is spectacular.
Another useful tidbit for your readers - if you’re lucky enough to spend a few days in Iguazu during a full moon, there’s a midnight, moonlit hike organized by the Park that absolutely rocks.
