There's a brand new PADI Dive Resort PIRATE DIVERS CLUB in Lassi Kefalonia 2km from Argostoli for those who are interested. It's located on the beach of the Mediterranee Hotel. Really nice dive sites with a RIB boat. Brand new equipment and excellent service. Wonderful shipwrecks from ancient to WWII, another recent shipwreck with trucks inside, caves, wall dives with lobsters, Dias (Zeus) a small island rock with a monastery on top where you can dive all the way around the rock on a single dive with lots of sea life, drift dives you name it. You're never rushed and often you get a boat tour as well. Sometimes the guys go for a cold one in a cool cantina. You're definitely have a blast diving with them. The stuff speaks really good english as they are native english speakers so communication with the stuff is never an issue. The prices are excellent and very competitive!
