Boat access from Porto Koufo is the normal way in; plan on a local operator for the transfer and briefing.
Errica cave is an open cavern dive off Porto Koufo with a broad surface-access opening, clear water, and a dramatic rocky chamber that leads into deeper water outside the entrance. The site suits divers who want a guided cavern-style route with strong visibility, shelter inside the opening, and concentrated marine life around the rock walls. It rewards controlled buoyancy and calm movement more than speed.
