Made up of close to 2,00 islands and islets, Ha Long Bay, in the Gulf of Tonkin, Viet Nam, forms a seascape of breathtakingly beautiful limestone pillars. It became a Unesco World Heritage Site in 1994. It's islands are mostly uninhabited, about 1,600 people live on floating houses in four fishing villages.
Ha Long Bay consists of 2 ecosystems...a tropical rainforest and a marine coastal ecosystem.
So, yet another interesting place that I would like to visit!
