Tien Son Cave

Tien Son Cave is a dry cave in the mountainside just above Phong Nha Cave. You can walk to it from the entrance to Phong Nha Cave (1,000m) – look for the sign at the foot of the stairs. This cave was discovered in 1935 by locals and named the Fairy Cave due to its extraordinary beauty, later it was called Dry cave to distinguish it from Phong Nha cave which is the water cave. The Chams used the cave’s grottoes as Hindu sanctuaries in the 9th and 10th centuries and till today, the remains of their altars and inscriptions can still be seen. This cave was last used as a hospital and ammunition depot during the War and thus one of the key entry points to the Ho Chi Minh Trail.
