Thiên Cung Cave

Thiên Cung Cave lies on Đầu Gỗ Island in the western part of Hạ Long Bay, about 20 metres above the sea and next to Đầu Gỗ Cave. Its floor of about 3,000 m² is filled with white stalactites and stalagmites, which gave it the name 'heavenly palace'; finds of the prehistoric Soi Nhụ culture were made at its entrance, and it opened to visitors in 1998.
