Popular around Lough Nacung
Delightful Dunlewy Lough is dominated by the majestic peak of Errigal. From here, the mountain appears as a great scree-covered dome, not the intimidating pyramid it appears as from the north. To the south-east is the spectacular glacial scoop of the Poisoned Glen, scene of a legendary battle between the sun god Lรบ and the supernatural Formorian pirate Balor.

A beautiful view of the Irish Fujijama. Near the hotel on the road there are a few archaic round stone posts which, together with the water, provide a beautiful foreground.

A magnificent mountain, but the climb is quite boggy at first, but later you need to be sure-footed.
