Outer Dingle Bay is a significant marine environment on the southwest coast of Ireland, forming the outer section of the larger Dingle Bay complex in County Kerry. This coastal waterbody is characterized by its open exposure to the Atlantic Ocean, contributing to the consistent swells and waves that make the area renowned for surfing. The bay's waters have been categorized as having 'High' water quality status. A defining geographical feature is the long sand spit of Inch Beach, which stretches approximately 5 kilometers and acts as a natural barrier, jutting into the sea between the outer Dingle Bay and the inner Castlemaine Harbour. This creates a dramatic landscape overlooking the Iveragh and Dingle Peninsulas. The area is adjacent to several protected sites, including the Blasket Islands Special Area of Conservation (SAC) and the Castlemaine Harbour Special Protection Area (SPA), indicating its ecological importance for marine life.
