Hito Tres Fronteras
This viewing point west of the town center stands high above the turbulent reddish-brown confluence of the Iguazú and Paraná rivers, which also form the Triple Frontera, or Triple Border Landmark. A mini pale-blue-and-white obelisk reminds you you're in Argentina. Take binoculars to see Brazil's green-and-yellow equivalent across the Iguazú River; across the Paraná is Paraguay's, painted red, white, and blue. A row of overpriced souvenir stalls stands alongside the Argentine obelisk.
