It rises in the Mullaghareirk Mountains on the Cork/Kerry border and flows through the County Cork towns of Mallow and Fermoy as well as the County Waterford towns of Lismore and Cappoquin before emptying into the Celtic Sea at Youghal, Co. Cork. The river is 170 km in length and is suitable for swimming at many locations along its length.

Martin Duggan Memorial Swim
The Martin Duggan Memorial Swim (Irish: Snámh Cuimhneacháin Martin Duggan) is held in the River Blackwater at Fermoy Rowing Club in County Cork. This is a 2 km race in which participants swim upstream (against a minimal current) for the first 1 km and then downstream for the second 1 km. The race is held annually in memory of Martin Duggan, a local schoolboy who drowned accidentally in the river on 12 July 2007, aged 14 years. In memory of Martin Duggan, the Martin Duggan Memorial Shield for the Youngest Swimmer has been awarded each year since 2009.
