A small rocky ridge of land is all that separates the larger Lough Conn from its southerly neighbour Lough Cullin, whose formation is explained in a colourful legend which tells how Celtic hero, Fionn MacCumhaill was out hunting boar with his two hounds, Cullin and Conn. The dogs were chasing a boar when water began gushing from the boar’s feet. The steady flow of water from the boar drowned Conn and Cullin while simultaneously forming two lakes: Conn and Cullin.
