The French named it “Le Tunnel” or Tunnel Grotto. The mouth of the grotto is so low one has to go by small boat to pass through.

To get there, tourists can hire canoesin Ðoan wharf (Hòn Gai, Hạ Long City) or take a coach to Cẩm Phả.

In front of the present-day mouth standsBa Cô (Three Girls) shrine in a towering piece of stone. Legend has itthat: “Once upon a time there were three girls who often went to the seatogether. One day, they caught a pouring rain and took shelter in agrotto. They found the scenery so captivating that they forgot the timeof rising tide. Locked up in the grotto, they passed away and becameWater God.”

Today, fishermen usually went to the shrine to pray for their bestowing favors on them.
