    Site Overview

    Arranmore Island off Donegal holds pristine kelp forests and wall dives with seals, big pollack and seasonal basking sharks (May-August). The SS Myra (1918) adds a 15-25 m wreck, and the clear west-coast water makes this a spectacular, remote site. Reached by ferry from Burtonport, Arranmore is wild, beautiful and rich in life for confident intermediate to advanced divers. The site rewards careful planning, good buoyancy and a respect for the power of the Atlantic, and remains a favourite among Irish divers.
