Since 1910, Gray Line has been the largest provider of sightseeing tours on the planet. After a century of trust, Gray Line Halong Cruise was born with a clear sense of WHY we were born! We, now in ours fifth year, have differentiated from others by a group of overnight boats ranging from 1 to 14 cabins in Halong Bay. We have faithfully brought comfort
in the harmony of traditional boat and deluxe facility to those visiting the natural heritage site – Halong Bay.
