Sung Sot Cave is on the same island with Trinh Nu cave. The path to Sung Sot is quite steep and is lined with shady trees. The cave has 2 chambers. The outer chamber is square and is often referred to as the waiting room.
The grotto is on Driftwood Island. Seen from afar, the entrance to the grotto appears to be blue, and has a shape similar to that of a jellyfish. After 90 steps up the island, the entrance is reached. The ceiling of the grotto is about 25 m. Hundreds of stalactites falling down from the roof of the grotto look like a waterfall.
