The River Bann (Irish: An Bhanna, meaning "white river") is a 42-kilometre freestone river rising from the southern slopes of Croghan Mountain in north County Wexford, near the County Wicklow border. It flows in a south-westerly direction through the villages of Hollyfort, Craanford, Camolin, and Ferns before joining the River Slaney approximately three miles north of Enniscorthy. With a drainage basin of 161 square kilometres and an average discharge of 3.18 m³/s measured at Ferns, the Bann is a fast-flowing river characterized by good pools interspersed with stretches that are heavily overgrown along the banks. It is primarily celebrated as a sea trout fishery, making it one of the notable migratory fish rivers in the southeast of Ireland. The river's name — derived from the Irish bán-abha — hints at its character: a lively, energetic watercourse that has shaped the landscape and the angling culture of County Wexford for generations.
