Built in 1847 as a famine relief project, this is a remarkable edifice, a 12m (39-ft.) tower built of solid stone nearly 5m (16 ft.) thick with a wooden arrow pointing to the mouth of the harbor. It is certainly interesting to look at, but the main reason for making the 1.6km (1-mile) climb to the summit of Carhoo Hill is not to see the tower, but the incredible views of Dingle Harbour, Connor Pass, and, on the far side of the bay, the peaks of the Iveragh Peninsula. This is a great place to get your bearings, but save a trip here for a clear day.
