This incredible triple threat border serves to separate the great countries of Brazil, Argentina, and Paraguay. The beautiful landmark is known as The Triple Frontier, and it's where the Iguazu and the Parana rivers converge in order to make one heck of a natural beauty. Nature is truly incredible in the way that it binds and seperates us. No man-made borderline could ever come close to something as grand as this.
To be honest, just looking at this picture makes us want to dive into that river and have ourselves a nice and relaxing swim. Probably not a good idea. though.
