Nestled in the starkly beautiful wilderness of County Mayo, Doo Lough (meaning "Black Lake") is a hauntingly serene glacial lake surrounded by the rugged peaks of the Mweelrea Mountains. Known for its dramatic scenery and poignant history—linked to the tragic Great Famine "Doolough Tragedy"—this remote spot offers a powerful sense of solitude and reflection. The scenic drive along the R335, with the lake mirroring the ever-changing skies, is one of Ireland’s most breathtaking routes. Ideal for hikers, photographers, and those seeking raw, untamed landscapes, Doo Lough embodies the wild soul of Mayo.
