Kerry is a maritime county in southwest Ireland in Munster Province Province, bounded on the southwest, west, and north by the Atlantic and the River Shannon estuary, on the east by County Limerick and on the southeast and south by Cork. It covers an area of 1814 square miles.
The coastline is unusually irregular and broken. Almost half of the county extends west into two large peninsulas, which are indented by bays and inlets. The best known of these bays are Ballyheige, Tralee, Brandon, Dingle, St Finan's and Ballinskellig. The Kenmare River forms a 30-mile deep estuary on the southwest. The great bay formed by the River Shannon is on the north. On the west coast are Smerwick, Castlemaine, and Valentia harbors.
The principal mountain range is MacGillicuddy's Reeks. The highest peak is Carrantuohill (3414 feet), the highest in Ireland. Kerry's lakes lie in the southern part. Tralee is the county town. Also important are Killarney, Ballybunion, Dingle, and Kenmare.
