The Blue Hole, also known as Blue Cave, in Gozo, is probably one of the most famous scuba diving sites on the Maltese islands. It’s a circular rock formation, a sinkhole in the limestone that measures around 10 metres wide and five metres across. The natural swimming hole is a sheltered pool, protected by a fringe of rock, thus making it the perfect location for a swim, snorkel and even a freedive, if you’re feeling slightly more adventurous. Situated right in front of where the Azure Window used to be, at the bottom of Dwejra Point, the Blue Hole is a short walk over rocky shore, and though you may stub your toe in the process, this natural swimming pool is more than worth it.
