Dunaff Hill [Cnoc Dhun Damh]

Rising steeply from the Atlantic at the northern edge of the Inishowen Peninsula, this rugged Marilyn dominates the entrance to Lough Swilly. While modest in height, its coastal position offers a wild, maritime character with views stretching across the water to the white tower of Fanad Head Lighthouse.

• •The name derives from the Irish Cnoc Dhun Damh, meaning 'Hill of the Fort of the Ox', likely referring to the ancient promontory fort situated on the cliffs nearby.
• •Standing at the mouth of Lough Swilly, the summit provides a clear sightline to the lighthouse at Fanad Head directly across the water and the Urris Hills to the south.
• •Despite its low elevation of 232m, it qualifies as a Marilyn because it is completely cut off from the higher interior mountains by the low neck of land at Leenan.
• •Given its exposed position on the Donegal coast, it is an excellent place to experience every variation of Atlantic weather before you have even reached the summit cairn.
