Sento Sé, Brazil

With a population of just 28,387, Sento Sé is a sparsely populated municipality that may prove a challenge for newcomers. The city covers an expansive 12,698.76 km2, with a mere 1.28 inhabitants per square kilometer. Bureaucracy is a persistent headache, as the city had to be entirely relocated in the 1970s due to the construction of the Sobradinho Dam. Despite its natural beauty, including amethyst deposits and the Ilha do Mocó island, Sento Sé is best suited for those seeking a remote, off-the-grid lifestyle.
