The Dark Grotto, which belongs to the Phong Nha Cave system, is 5,258m long and 80m tall and is home to thousands of stalactites in various shapes and colours as well as several indigenous species of bat and swallow.

This Tet (Lunar New Year) festival marked the reopening of Tien Son Cave to tourists, after a 10-month tourism renovation project at the cave. The mouth of Tien Son Cave is 1,000m from the mouth of Phong Nha Cave which is also known as the Water Grotto or Lower Phong Nha while Tien Son is known as the Dry Grotto or Upper Phong Nha.
During the first four days of the Tet, the park received more than 3,000 tourists, including more than 500 foreign tourists.
