County Kerry faces the Atlantic Ocean and, typically for an 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.
Dingle Peninsula contains two of the three highest mountains in Ireland, Carrauntoohil, part of the Macgillycuddy's Reeks range and Mount Brandon, part of the Slieve Mish range.
The Lakes of Killarney in the centre of the county are a scenic tourist attraction.
Just off Kerry's coast are a number of islands, including the Blasket Islands, Valentia Island and the Skelligs. Skellig Michael is a World Heritage Site, famous for the medieval monastery clinging to the island's cliffs.
