Lough Nafooey, near Leenane, is one of Connemara's most photographed sights, because of the haunting beauty and it is a hidden gem of Ireland. It lies along the border to County Mayo and lined by the rugged Maumturk mountains to the south and Mayo's Partry mountains to the North.
The lough is a rectangular glacial lake and is renowned as the site of the ancient "Finny volcano" (490 million years ago). Some volcanic rocks, including pillow lavas and breccia, can be found in the area.
The locality offers a good range of walks catering for all walkers.
It is said that the clear waters of the lake are home to An Capall Uisce, a mythical Celtic creature: the Water Horse.
