Hang Bo Nau, also known as "Pelican Cave" is named so due to the herd of pelicans that filled the cave in the past. The cave has a monster mouth opening with the stalactites and stalgmites of strange shapes falling down from the ceiling looking like sharp teeth. You can stand at the entrance and admire the stunning scenery of Halong Bay.
