Kerry faces the Atlantic Ocean and, typically for an Eastern-Atlantic coastal region, features many peninsulas and inlets: principally the Dingle Peninsula, the Iveragh Peninsula, and the Beara Peninsula, shared with neighbouring County Cork. The county is bounded on the west by the Atlantic Ocean and on the north by the River Shannon.
The Ring of Kerry on the Iveragh Peninsula is a popular route for tourists and cyclists. The pedestrian version is the scenic Kerry Way which follows ancient paths generally higher than that adopted by the Ring of Kerry.
Kerry is one of the most mountainous regions of Ireland and contains two of its three highest mountains, Carrauntoohil, part of the Macgillycuddy’s Reeks range and Mount Brandon, part of the Slieve Mish range.
