Broad Lough is a significant estuarine system and coastal wetland complex situated just north of Wicklow town on Ireland's east coast. It forms a key part of the 15-kilometre Murrough Wetlands, the largest coastal wetland in the region, characterized by a serene, wild, and often remote environment. The estuary runs parallel to the coast, with its waters ultimately draining into the Irish Sea through the Leitrim River at Wicklow Harbour. This area is recognized as a nature reserve, offering a unique blend of estuarine and near-shore marine habitats that support a variety of fish species.
