The team at Black Rock Dive Centre in the Aeolian Resort offers full training at all levels - including PADI certification - along with a number of activities for less knowledgeable divers and children. The water here is clear and calm with excellent visibility, so there's plenty to attract both novice and seasoned scuba enthusiasts. Guests of the resort can book through the front desk, but the Centre is also open to the public. Packages range from $40 to $600.
