From Gozo, we return now to Malta's village Weid-iz Zurrieq for a ride in Dghajsa to the Blue Grotto. The Blue Grotto or Iil-Hnejja in Maltese is a cavern 40 meters in circumference surrounded by turquoise waters, a paradise for divers and marine life. The deepest point is called the Bell Tower Cavern and is 26 meters under the sea.
