Coruripe, Brazil

With a population of just 49,240, Coruripe is a small, remote municipality on the southern coast of Brazil's Alagoas state. At 913 square kilometers, it's the largest municipality in Alagoas, but that speaks more to the state's sparse development than any urban sprawl. Bureaucracy is a persistent headache, as evidenced by the city being the smallest among Brazil's largest municipalities. The sole notable resident is supercentenarian Yolanda Beltrão de Azevedo, who at 111 years old is the oldest living person in the country. For those seeking a quiet, low-key seaside existence far from the crowds, Coruripe may fit the bill - but the isolation and red tape are not for the faint of heart.
