US$34 million had been spent on Six Senses Con Dao covering 12ha on Con Son, the largest island of the archipelago, which is reached by daily hour-long flights from HCMC, Six Senses Resorts & Spas said in a statement.

The company, together with its development partner Indochina Capital, built its 50 villas along a mile of sandy beach using building materials from natural, sustainable sources.

The Con Dao archipelago remains untouched by the modern world and more than 80% of it is national park, including a 140km² marine reserve.
