Thay Cave
Thay cave is about 23 km from Tuan Chau International Marina and 18 km from Ha Long International Passenger Port. It is about 2500m2 wide with the system of primitive and fanciful stalactites and stalagmites. In front of the entrance is a 70m-long sandy beach, an ideal place to develop tourism services such as sea bathing, relaxing and kayaking.
