I'm spending this weekend at Iguazu Falls, the mammoth waterfalls at the border of Brazil, Argentina and Paraguay. It's a truly spectacular sight, more powerful than Niagara and wider than Victoria (the falls, not the queen).
Perhaps even more interesting than visiting the falls has been exploring the three towns at the 'triple frontier', Foz do Iguacu, Puerto Iguazu and Ciudad del Este. It is essentially one large urban conurbation spanning three borders. I've taken to collecting visits to sites like this. It's my fourth triple border, after NL-BE-DE, CH-FR-DE and CH-LI-AU.
