The Atlantic breathes cool and steady as dusk settles over a narrow West Cork cove—salt on your lips, sand still warm where daylight held it. When darkness deepens the water starts to react, each small movement igniting a soft blue-green trace that seems to answer the hand that parts it. Guides keep a respectful hush; you slip into shallow water with a wetsuit and buoy, and the sea, playful and ancient, dares you to move.
