The River Tolka is a roughly 14-mile waterway that rises in the gently rolling farmland near Dunshaughlin in County Meath, flowing in a southeasterly direction through the northern stretches of Dublin City before emptying into the Irish Sea at Eastpoint. As the second largest river in Dublin after the Liffey, the Tolka is fed by a network of smaller streams and tributaries — quiet rural streams in Meath as well as more than a dozen inflows within the city itself. As it approaches Dublin Bay, the river becomes tidal, its flow influenced by the ebb and surge of the sea. Despite decades of urban pressure, the Tolka has undergone a remarkable ecological recovery and today offers genuinely rewarding trout fishing in an accessible urban setting, with the added excitement of occasional encounters with returning Atlantic salmon and sea trout.
