The Dingle Peninsula stretches 30 miles (48 kilometres) into the Atlantic Ocean from Ireland's south-west coast. The peninsula is dominated by the range of mountains that form its spine, running from the Slieve Mish range to Mount Brandon, Ireland's second highest peak. The coastline consists of steep sea-cliffs, broken by sandy beaches, with two large sand spits at Inch in the south and the Maharees to the north. The Blasket Islands lie to the west of the peninsula.
