As recently as 2006 scuba diving in the Greek Islands was severely restricted in a bid to prevent people from plundering the treasures that lie all over the Mediterranean sea floor. Now diving regulations have been eased and the move has prompted a huge rise in diving clubs throughout the Greek islands.
Indeed there are not now many popular Greek islands that do not have at least one scuba diving centre.
And because Greek Island dive sites have been free of interference for so long they have now become must-visit destinations for keen scuba divers from across the world.
With more than 240 inhabited Greek islands and a long history of seafaring there are a significant number of wrecks to explore, not to mention the underwater reefs, caves and walls.
What makes diving in the Greek Islands so exciting is that on most dives there is a good chance of finding historic artefacts.
Divers get the chance to be the first to see underwater history. But it is still look, don't touch. Disturbing or taking underwater finds is illegal and all finds should be reported.
Although there is something to interest everyone on any of the Greek islands there are a few sites that stand out from the crowd when it comes to scuba diving.
Mykonos has some of the best dive sites in the Mediterranean, from the Dragonisi caves with their remarkable rock formations to the wreck of the Peloponisos which sank off Prasonisi in the 1930's.
Naxos is known for the wrecks of a Beaufighter torpedo bomber from World War II and an Arado 196 German seaplane as well as the Dome, an ethereal blue cavern teeming with marine life.
Off nearby Paxos is the sunken minesweeper HMS Regulus. The wreck has a massive anchor and attracts a considerable amount of marine life.
Crete has a ring of excellent dive sites and is one of the best laces to spot larger creatures such as bluefin tuna. The clear waters and underground caverns and canyons provide exceptional photo opportunities.
Add to the mix the laid back way of life, the incredible beaches, unforgettable scenery and the Mediterranean summer sunshine and it's not hard to see why the Greek islands are turning into a major dive site centre.
