The Blue Hole, in Dwejra, is a unique geological formation, making it one of the island’s most sought-after diving spots. This natural wonder, at first sight looks as if it is carved into the surrounding rocks. Nevertheless 10 metres below surface of the clear blue waters, one can find an underwater natural arch that is a doorway leading to the open sea. It’s a remarkable diving spot one of the most sought-after, in the Maltese islands, which can be tackled by divers of different levels.
