Argentina

It's apparent why Argentina has long held travelers in awe: tango, beef, gauchos, fútbol, Patagonia, the Andes. The classics alone make a formidable wanderlust cocktail.

The Argentine park has plenty to offer, and involves a fair amount of walking. The spread-out complex at the entrance has various amenities, including lockers, an ATM and a restaurant. The complex ends at a train station, where a train runs every half-hour to the Cataratas train station, where the waterfall walks begin, and the elevated walkway Garganta del Diablo.
