Nearly 2,000 limestone islands rising from emerald water, a name that genuinely translates to "descending dragon," and an overnight cruise experience unlike anywhere else.
Ha Long Bay is a UNESCO World Heritage Site featuring nearly 2,000 limestone karsts and islets rising dramatically from emerald water, a genuinely unique geology found in very few places on Earth.
