Letterkenny - Holy Well

The Rock of Doon is found 2mi/3km west of Kilmacrenan, northeast of Gartan Lough. It is a large slab of stone with a flattened upper surface which was the place of coronation of the O'Donnell kings. It is well worth climbing the rock for the sake of the extensive views of the surrounding moorland from the top. At the foot of the rock is the Holy Well, visited by pilgrims for the sake of its healing powers.
