Muckross LakeApprox. Time: 2 hours
Activity Level: Easiest

Muckross Lake is the deepest of the lakes with a maximum depth of approximately 75 metres (250 feet) close to where the steeply sloping face of Torc Mountain enters the lake. At lake level, there are many caves in the limestone which are formed by the dissolution effect of acidic waters on the exposed rock, especially when combined with wave action. Nowhere are these caves more marked than on the northern shore of Muckross Lake.
