There's more underfoot than just supple sand at Itaúnas, on the southeast coast of Brazil. Beneath the golden domes lies an old fishing village that was swallowed by the dunes in the 1960s. Today the rebuilt town – now set a half-mile back from the Atlantic Ocean – is your departure point for hiking the 15-mile coastline of Parque Estadual de Itaúnas, a wilderness populated by jaguars, monkeys, sloths, and sea turtles. As evening falls, return to the beachfront Casa da Praia to partake in the nightly forr – dance parties – best initiated with a few caipirinhas.
