Caves
Halong Bay is famed for its many breathtaking caves and grottoes including the 10,000 sqm Surprise Cave and the scenic Luon Cave which opens up to a stunning mountain lake.
Sung Sot GrottoEarly French tourists who wandered among the 10,000 square meters of this cavern dubbed this space “Grotte des Surprises”, or Surprise Cave. The grotto features thousands of stalactites and stalagmites. Paths, lights and signposts guide you through two caves which continue to offer yet more twists, turns and, yes, surprises throughout.
