Perhaps the top WW II wreck dive in Mediterranean, British Overseas Patrol submarine HMS/M Perseus, (N36) lies virtually intact on the sandy bottom, at 52 meters depth, about a mile off the south coast of Kefalonia.

Perseus submarine is not only among the most impressive wreck dives a diver can experience, but has an amazing history as well. The vessel was on combat patrol in December 1941, and while cruising at the surface at night hit an Italian naval mine and sunk. From the crew of 59 only one, the Royal Navy leading stoker John Capes managed a daredevil escape from a depth no one has attempted before, swam his way to Katelios and with the aid of locals escaped capture from Italian and German occupation forces and finally transferred in Turkey. While legendary in Royal Navy, almost nobody believed his adventure until in 1997 a team of Greek divers located the submarine and verified details of his described escape.

The divers approaching the submarine encounter a magnificent vessel 88 meters long, with a large conning tower, the ship’s gun and the rear hutch still open indicating the escape route of John Capes, while a look in the interior is possible. Among other things, the torpedo tubes and the ship’s propellers and rudder are visible.

The submarine is practically an artificial reef and colorful sponges, small fish and aquatic creatures take shelter here, while predators like amberjacks and snappers are frequent visitors.

The average depth or the dive is 40 m, while the max is 50, reserving the submarine for experienced and technical divers. The visibility is usually greater than 25m while temperature ranges between 18-24 C in summer months, depending on depth. Occasionally there may be strong currents close to the surface. Boat ride duration 15′.

Out of the seagrass meadows (“Posidonia oceanica”) a lone reef rises, a death trap to ancient vessels passing through the area. At least 2 of those wooden merchant ships once roaming the Mediterranean, have found their final resting place here, scattering their ballast stones, lead and bronze parts of their hull and rigging and scores of amphorae – their primary cargo, proving the area a puzzle to seamen through the ages.

On the underside of a long shallow rocky ridge, a small yet impressive underwater cave awaits to be explored. The dark chamber in the rock features two side-openings and one on the top acting as a skylight shedding ample light into the interior, rewarding the daring diver with spectacular views. Also a variety of fish and quite often Loggerhead sea turtles are frequent visitors to the site.

The average depth or the dive is 7 m, while the max is 12 m, appropriate for divers of all levels.

The usual visibility is 25 m and temperature ranges between 22-27 °C in summer months. Occasionally a weak surface current may be encountered. Boat ride duration 5′.

Located at the northern extents of the Kakava reefs, this site is the most representative example of Mediterranean seafloor landscape and biodiversity in shallow coastal waters and provides excellent chances for u/w photographers. Collapsed caves and holes, along with meadows of Posidonia sea grass create the perfect environment for parrotfish, wrasses, gilt head breams, scorpion fish, young groupers and snappers. Around the reef fragments of ancient clay jars (“amphoras”) can be spotted, however the highlight of the site are the 12 enormous, probably Byzantine era anchors, presumably ditched by a ship struggling to escape crashing on the reef.

The average depth of the dive is 7 m, while the max is 12 m, suitable for divers of all levels.

The usual visibility is 25 m and temperature ranges between 22-27 °C in summer months. Occasionally a moderate surface current may be encountered. Boat ride duration 5′.
