Designated a UNESCO World Heritage Site in 1994, Ha Long Bay’s more than 1,600 islands and islets form a stunning seascape of towering limestone pillars surrounded by biodiverse waters, including a vast array of marine algae and more than a thousand species of fish. The bay is also home to 163 species of coral, which provide a colorful undersea home to many of the aquatic inhabitants. Terrestrially, the islands’ dense rain forest ecosystems support various rare species of birdlife and mammals, such as deer, weasels, squirrels and white-tabby and red-haired monkeys.
