Alenquer, Brazil

With a population of just 52,856, Alenquer is a sleepy riverside town that offers little to entice the average expat. The city is served by a small airport, but that's about the extent of its infrastructure. And while the surrounding nature reserves may appeal to eco-tourists, the persistent bureaucracy and administrative headaches are a significant deterrent.

Alenquer's remoteness on the northern bank of the Amazon River means it's a poor choice for those seeking an easy transition to Brazil. The town's isolation and limited amenities make it better suited for hardy adventurers or retirees seeking a simple, off-the-grid lifestyle - if they can navigate the red tape.
