One of the most spectacular dive destinations in the Maltese Islands is the Blue Hole. The entrance point alone, which originally housed the iconic Azure Window, is one-of-a-kind. On March 8, 2017, the Azure Window regrettably collapsed. Your dive will take place between wind-eroded rock formations and water with steep walls, providing access to the open sea. The spectacular arch, which begins at a depth of 8 meters, the massive 15-meter-deep cave at the bottom, and the vertical tunnel or Chimney are all very stunning. The left reef leads to the Chimney. It begins at a depth of 18 meters and ends at a depth of 4 meters at the Coral Gardens, where you can exit the ocean.
