The name Bo Nau is associated with the fact that pelicans often take shelter here. Located in a complex, including Sung Sot cave, Luon cave, Ti Top Island, and Trong cave; however, Bo Nau Cave has not yet been exploited, therefore, the cave still retains its pristine.
The mouth of Bo Nau Cave is quite wide with the size of 5-7 meters. It’s in the shape of arch and has many stalactites falling down from the ceiling. Sitting in the cave, you can have a large view of the bay and remote island as far as your eyes can see, which seems like standing in the monster’s mouth with sharp teeth and seeing magnificent scenery outside.
The space inside covers an area of 200 square meters. The foundation of Bo Nau Cave is flat with various stalagmites growing up in different sizes and shapes. With colorful lights from the grotto entrance and mountain chinks as well as dripping sound by various water drops from the cave ceiling, Bo Nau is really like an unreal paradise, which can steal any visitors’ heart. Right on the entrance is three blocks of stone. They look like a sculpture about three fairies playing chess.
