Dingle Bay, or Bá an Daingin, is a significant Atlantic bay on the southwest coast of Ireland in County Kerry. It stretches approximately 40 kilometers (25 miles) from its head in the northeast to its open ocean entrance in the southwest. The bay is relatively narrow at its head, about 3 kilometers (1.9 miles) wide, but broadens to around 20 kilometers (12 miles) at its mouth. It is flanked by the dramatic Dingle Peninsula to the north and the Iveragh Peninsula to the south. The bay's geography includes a protected lowland estuary area with tidal flats at its head, where the River Maine and River Laune enter. Prominent features include the extensive Inch Strand, which reaches across the bay, and the settlements of Dingle, Ventry, Annascaul, Glenbeigh, and Killorglin along its shores. The bay's waters are historically rich and support a variety of marine life.
