This is the largest and perhaps the most beautiful of the upper lakes. It is2 miles long and about a mile wide, and is at the head of the Cummeragh system. The shallow shore line gives the best fishing for sea trout and brown trout especially along the north shore beneath the woodland. Salmon are distributed throughout. To fish this lough is truly an experience.
Fishing is by a boat and available by ticket.
There is a sense of awe about this lough, as from its open shallows where the river flows out, it sweeps into a narrow arm defended by steep mountains and it is dominated by a large wooded island. There are also Salmon. Fishing is from boats and available by ticket. This lough lies immediately below Cloonaghlin separated by a river 250 yds. in length. It is a lough of almost equal length and breadth and has an area of about 100 acres.
