El Banco, Colombia

This riverside municipality of 59,594 people is no tourist destination. The streets are clogged with more motorcycles than cars, and the bureaucracy is a persistent headache - the ideal would be a bypass to divert traffic from the urban area. Summers are short but stifling, with temperatures climbing above 39°C. While the city has good connections to major hubs, the airport is rarely used, and the public transport system is nonexistent. El Banco is for the hardy, not the faint of heart.
