Mountnugent 26 is one of the designated fishing zones on Lough Sheelin, a celebrated trout lake situated in County Cavan, Ireland, approximately 120 kilometres northwest of Dublin. Lough Sheelin is widely regarded as one of Ireland's premier wild brown trout fisheries, and the Mountnugent area on its shores provides anglers with access to some of the lake's most productive and scenic waters. The lake benefits from a rich aquatic ecosystem that supports exceptional trout populations, drawing fly anglers from across Ireland and beyond throughout the season, which runs from 1 March through 12 October.
