Dau Go Cave, also known as Wooden Stakes Cave, is one of the most magnificent caves in Halong Bay, Vietnam. Located on Dau Go Island, this ancient limestone cave is famous for its vast chambers, colorful stalactites, and intriguing history. Spanning over 5,000 square meters, the cave is divided into three main chambers, each filled with natural rock formations resembling animals, mythical creatures, and symbols. The name “Dau Go” refers to the wooden stakes used by General Tran Hung Dao to trap Mongol invaders in the 13th century, said to have been stored here. As sunlight filters through the cave’s entrance, it illuminates the formations in a kaleidoscope of colors, creating a surreal experience. Dau Go Cave is a must-visit for those exploring the mystical beauty of Halong Bay.
