Easy 4.7km trail starting opposite the Tourist Office in Cong and crossing the Cong river before passing several caves including Pigeon Hole Cave. A steep flight of limestone steps leads down to the mouth of the cave, a fairly large chasm over 12 feet wide covered in bushes and where the pigeons like to nest.

Cong–the gateway to northern Connemara is a small village situated between Loughs Corrib and Mask and straddling the border of counties Mayo and Galway. Geographically, it is also on a border – the lands to the east are very productive agriculturally. Those to the west are less fertile and are dominated by large expanses of carboniferous limestone. Lough Mask, to the north, is higher in elevation than Lough Corrib to the south and the water makes its way both over and underground. Man-made features are also very evident in the environs of the village. Almost immediately after leaving the trailhead for the looped walks, you pass through the ruins of the Augustinian abbey which was the residence of the last High King of Ireland.
