The Avonmore River is a classic freestone river rising at the foot of the Wicklow Mountains and flowing southeast for approximately 20 miles through a mountainous landscape of plains and valleys, some areas surrounded by forests, before joining the Avonbeg at the "Meeting of the Waters" upstream of Avoca. The river has retained its natural, undrained characteristics, creating a diverse fishery with stretches that alternate between deep, slow-flowing glides and areas of fast-flowing riffles and runs, culminating in deep pools. This beautiful watercourse supports a wild brown trout fishery within the broader Avoca-Avonmore catchment, an area historically impacted by mining but now the focus of conservation efforts.
