Isolated from the mainland, the Con Dao Islands are one of the star attractions in Vietnam. Long the Devil’s Island of Indochina, the preserve of political prisoners and undesirables, this place is now turning heads thanks to its striking natural beauty. Con Son, the largest of this chain of 15 islands and islets, is ringed with lovely beaches, coral reefs and scenic bays, and remains partially covered in thick forests. In addition to hiking, diving and exploring empty coastal roads and deserted beaches, there are some excellent wildlife-watching opportunities.
