Lying on Dau Go Island, Thien Cung Cave is considered as the most beautiful primitive cave in Halong Bay.
Approximately 4 kilometers from tourist wharf and 8 kilometers from Halong City, Thien Cung Cave appeals to travelers by its stunning system of stalactites and stalagmites with different forms and shapes. Passing through a narrow door, travelers may be surprised by how large the inside space is. Especially, the deeper you come, the more astonished you get. The animated and splendid beauty of stalactites and stalagmites is explained by an old love story between a Dragon Prince and a beautiful lady. It has been said that the cave is a blissful wedding party in a heavenly palace of the Dragon Prince and the girl with the attendance of different kinds of animals (elephants, snakes, lions, birds…).
