Six Senses, Con Dao
The Con Dao archipelago lies offshore from Ho Chi Minh City, in the far south of Vietnam. Though their isolation makes them tricky to reach, they reward intrepid travellers with forested hills, scenic bays and coral reefs teeming with tropical fish. The first five-star resort to make the journey across from the mainland comes from Six Senses. Its all-villa hotel on the island of Con Son, is best visited between May to October, when turtles come to hatch, or from February to July when the waters are clearest for diving.
