Lough Ramor is a large glacial lake situated just south of the town of Virginia in County Cavan, Ireland, approximately 90 meters above sea level and only 1.5 hours from Dublin. Covering roughly 713–741 hectares and stretching approximately 4 miles long with an average width of half a mile, it is the largest lake in the Boyne catchment. The lake was formed by melting ice at the end of the last Ice Age, approximately ten thousand years ago, and sits on a bed of sandstone surrounded predominantly by rich agricultural pasture. The River Blackwater both flows into and out of Lough Ramor, carrying its waters approximately 3 miles through County Cavan before entering County Meath. Lough Ramor is a proposed Natural Heritage Area (pNHA), and the Blackwater into which it drains is designated a Special Area of Conservation (SAC) under the Natura 2000 wildlife habitat conservation programme. The lake is well known as an excellent pike and coarse fishery, drawing anglers from across Ireland and beyond, with brown trout fishing also available during the mayfly season.
