Scuba diving at Barracuda Reef in Zakynthos

About This Site
Barracuda Reef is the Keri Peninsula's classic 'big-fish' deep reef, worked by the Keri and Marathias dive centres off the Cape Marathia headland on the exposed south-west corner of Zakynthos. A single rock breaks the surface above a limestone reef that begins in the shallows and rolls out over a shelf at around 10-18 m before the bottom turns to sand and drops abruptly away past 50 m into the open Ionian. Large groupers hide in the wall's holes and crevices and turtles, octopus and moray are common on the reef, but the site earns its name at the drop-off: when the current runs, schools of barracuda gather behind the offshore rock, with tuna, amberjack and dentex hunting the bait shoals below. It works as an accessible reef dive for most certified divers, with the deeper wall as an advanced option.

Barracuda Reef sits on the seaward south-west edge of the Cape Marathia / Marathias headland, the exposed corner of Zakynthos, in the reef channel just south of the two Mizithres rocks. The Marathia cliffs and shore to the north and north-east, together with the larger Mizithra rock immediately to the north, shield the site from northerly and north-easterly wind and chop, so the N-NNE-NE-NW-NNW sector is effectively blocked. The open window faces the Ionian to the south and south-west: the SE-through-SW arc is fully exposed to the dominant west-to-south-west Ionian swell and to any southerly blow. The W and WNW are only partly shadowed by the smaller Mizithra rock and the distant Keri cape, and the eastern side is partly open across the mouth of Laganas Bay. As a headland-edge reef with a drop-off it is dived in calm summer conditions; a southerly wind or a west-south-west swell builds surface waves and reinforces the current at the drop-off, and can force trips to switch to more sheltered Keri sites.
