Ha Long Bay is a UNESCO World Heritage Site in northern Vietnam, known for its limestone karsts, emerald waters, and tucked-away caves. The only way to experience its scale and beauty is on a cruise—sailing between islands, visiting floating villages, and stopping at hidden coves.

“Ha Long” means “Descending Dragon.” Legend says a dragon descended from the mountains, carving valleys with its tail and creating the bay to protect Vietnam from invaders.
Ha Long Bay has been home to prehistoric cultures like Soi Nhu, Cai Beo, and Ha Long. Archaeological sites reveal tools, pottery, and evidence of early seafaring communities.
