First up on our list of the most beautiful lakes in Ireland is Lough Cullin in County Mayo.

Lough Cullin appears in a Celtic Myth in which Fionn mac Cumhaill comes across a wild boar while hunting with his wolfhounds, Cullin and Conn. As they chase the boar, water pours from its feet, and as days pass, a lake appears.

Conn overtakes Cullin but drowns in the lake ahead before the boar swims back to safety. The second hound, Cullin, drowns further south. Legend has it, Lough Cullin and Lough Conn were thus created.

9. Lough Corrib, Co. Galway – for game angling

Lough Corrib drains via the Corrib River into Galway Bay and is a must-see for anyone who loves the West.
