Lough Arrow
Lough Arrow, at the foot of the Curlew Mountains, is 22 kilometres from Sligo town on the border between the counties of Sligo and Roscommon. It is the largest lake in Sligo, measuring 8 kilometres long and 2.5 kilometres across at the widest points. The lake is fed from water spring wells.
The lake is drained by the Ushin River which flows into the Owenmore River near Ballysadare and on to the Atlantic Ocean. Lough Arrow boasts some of the finest wild trout fishing in Europe and is an anglers Mecca during the mayfly season.
