According to the article, the bay’s natural beauty makes it one of Vietnam's number one tourist sites, adding that it is also a UNESCO World Heritage site. “The best way to see Ha Long's awe-inspiring limestone towers is by boat. In fact, many tourists stay overnight on a boat in the bay,” it said. Ha Long Bay literally “descending dragon bay”, was twice recognised as a World Natural Heritage site by UNESCO in 1994 and 2000. The geo-diversity of the environment has created biodiversity, including a tropical evergreen biosystem, oceanic and sea biosystem. 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./.
