Until recently strict Greek laws limited diving, providing legal access to only 1% of Greece's potential diving spots. This way local governments tried to protect submerged historical sites like ruins and shipwrecks. However, nowadays more and more new diving spots are becoming available to the public.
Regarding marine life, the Mediterranean is often said to have scanty fauna, though still, divers verify the abundance of tuna, barracuda, octopus, cuttlefish, squid, oysters, mussels, and other fish and shellfish. Diving hotspots in Athens are located on the southern coastline around Voulga, Eni, Sounio, and also in Kineta, Neraki, and along the other shores of Attica. The best season to dive or snorkel is May, June, and September.
