There are a lot of natural caves at Halong Bay. The largest one is Hang Đầu Gỗ (Wooden Stakes Cave), but where we visited is Hang Sửng Sốt (Amazing Cave). This cave is located on Bo Hon Island with a small entrance from cliff and two large chambers. Our guide brought us to Bo Hon Island in heavy rain. After enter Amazing Cave, we could luckly keep us most of the time dry and start to make photos. Although we have visited many Karst caves, Amazing Cave still can surprise us with its beauty.
Get in the cave, safe to use my camera now.
Timeline of geologic evolution (From: wikipedia)
Some of the most remarkable geological events in Hạ Long Bay’s history have occurred in the last 1,000 years, include the advance of the sea, the raising of the bay area, strong erosion that has formed coral, and, pure blue and heavily salted water. This process of erosion by seawater has deeply engraved the stone, contributing to its fantastic beauty. Present-day Hạ Long Bay is the result of this long process of geological evolution that has been influenced by so many factors.
Due to all these factors, tourists visiting Hạ Long Bay are not only treated to one of the natural wonders of the world, but also to a precious geological museum that has been naturally preserved in the open air for the last 300 million years.
