|Ha Long Bay on a beautiful spring day.
View from "Hang Bo Nau" or "Pelican Cave". Long ago, the cave was home to thousands of pelicans and gulls but today as more visitors and people inhabit the surrounding islands the birds have left. The traditional fishing junk is now a rare find. Ha Long Bay, recognized by UNESCO as a World Heritage, is called "Bay of the Descending Dragon" because sighting of dragons were reported by ancient times fishermen. 3000 islands of dolomite and limestone that formed here between 300 and 500 million years ago, cover a 1500 square km area (579 square mile).
