For day 2 of my Iguazu adventures, I actually did not go to “the” falls. Instead I chose to take a day to wander Senedero Macuco. A nature trail which takes about an hour to reach the solo Salta Arrechea waterfall. This is the one place in the park where visitors have the opportunity to swim. The trail also provides an opportunity for viewing wildlife like capuchin monkeys, rare birds, lizards, unusual insects and masses of butterflies.
