In order to break up the 19-hour bus ride, just a bit, we chose to stop in San Ignacio, home to some of the most well-preserved Jesuit missions in South America. Settled in 1696, the Jesuits left the mission in 1768 after begin expelled. Although the mission was destroyed in the early 19th century it remained lost in dense vegetation for nearly a century, and restoration began some 40 years later. The UNESCO World Heritage Site is now the second-most visited place in Northeast Argentina, seriously lagging behind Iguazu Falls.
We paid the "special" price for foreigners (about $22 USD) after a 10-minute wait in line. Regardless, the spectacle is well worth the price of admission. There are a handful of different trails on the Argentine side. We started off with the Circuito Superior, or Upper Circuit. This walk provided panoramic views of the falls from the Upper Iguazu River. Next we hit up the Circuito Inferior, which take you much closer to some of the same falls as the Upper Circuit, however from much lower, allowing you to cool off a bit in their misty expanse. After eating our packed lunch we headed for the highlight of the day: Garganta del Diablo (aka The Devil´s Throat.)
where the borders of Brazil Argentina and Paraguay converge. Honestly, it´s nothing spectacular to see...but kind of cool to realize that you are only a stone´s throw away from two other countries. Each country is marked by an obelisk painted the same colors as its flag, making it easy for visistors across the river to differentiate which country they are looking at.
