Halong Bay

A UNESCO World Heritage site of around 1,600 limestone karst islands rising from the Gulf of Tonkin in northern Vietnam. The bay draws millions of visitors annually by cruise boat, and UNESCO deployed an expert mission in 2024 over concerns about unchecked coastal development threatening its heritage values.

Movement through central areas is slow — expect to dodge and wait. Lines at major sights routinely exceed 1–2 hours without pre-booking. Iconic views are difficult to photograph without crowds in frame. Local residents have publicly raised concerns about visitor volume.
