The principal headlands from N. to S. are Kerry Head, Brandon Head, Slea Head, Bray Head, and Bolus Head. The largest islands are Valentia and the Blasket group. The greater part of the surface is bleak and mountainous, but there is also much romantic scenery. The principal summits are Carrantuohill or Carn Tual (3414 ft.), in the range of Macgillicuddy's Reeks, the loftiest mountains in Ireland; Bautregaum, 2784 ft., and Mangerton, 2751 ft.

The ores of iron, lead, and copper are abundant in the S.; slate and flag-stone are quarried in Valentia. The chief crops are potatoes, oats, and turnips. The coast fisheries are extensive, and give employment to a large number of men and boys.
There is now direct railway communication from Tralee and Killarney to Cork and Limerick.
