The Au Co Luxury Cruise takes you further, exploring Untouched Island so you can experience its distinctive geology, local history and endemic flora and fauna. Unlike more common three-day two-night cruises which use transfer boats, guests will remain on the same Au Co for the entire trip to have the best Halong Bay tour experience. Aboard The Au Co Luxury Cruise, a luxury cruise means a safe cruise. Unwilling to compromise the customers' experience, aboard the Au Co we have set new benchmarks in Halong for both luxury and safety. The Au Co makes sure to delivery the full comfort and memorable cruise experiences for passengers.
