Diving in Ireland
Including Achill Island, Bantry Bay, and Dingle Peninsula. On the map.
The vibe
Submerged explorations here center around legendary shipwrecks and dramatic underwater topography swept by oceanic currents. The diving season peaks during the calmer, longer daylight months of summer, though Atlantic swells can dictate the schedule at a moment's notice. Operations are run through tight-knit local clubs and independent centers rather than massive resort fleets, giving every trip a rugged, expedition-style feel.
