Plongée à Fastnet Rock — Ireland

Fastnet Rock, Ireland's most southerly point, rises dramatically from the open Atlantic beneath its iconic lighthouse. The underwater walls plunge into blue water where blue sharks and ocean sunfish pass in summer. Weather windows are narrow, so every successful dive feels like an achievement.
