"According to scientists, the geological layer in Ha Long Bay was covered with a layer of slow-growing limestone for more than 500 million years, then weathered by the sea, broke up and formed the islands that are today", Live Science noted.
Ha Long Bay was originally recognized as a World Natural Heritage by UNESCO back in 1994 and was later re-recognized for the second time in 2000.
In 2018, Ha Long Bay made it into the top 15 Instagrammed global cruise destinations based on a survey of 1.8 million posts tagged on various ships and ports by travel cruise site SeaHub.
In 2019, British travel magazine Rough Guides included Vietnam's Ha Long Bay in its selection of the 100 most beautiful places to visit next year. It describes "the scattering of limestone pinnacles jutting out of the smooth waters of Ha Long Bay", around four hours east of Ha Noi capital, as an "incredible sight".
