Bo Nau Cave is an extremely impressive land for both domestic and international tourists.
The mouth of Bo Nau cave is quite wide with a size of 5-7 meters. The cave is dome-shaped and has many stalactites falling from the ceiling
If Dau Go Cave is completely inside the island, then Bo Nau opens its mouth on the other side of the island
From the cave, tourists will get a unique view of Ha Long Bay, which looks like standing in the mouth of a monster with sharp teeth and seeing the beautiful scenery outside.
