Course

The Silver rises on the northwestern slopes of Baureigh Mountain (486 m) and descends to Cadamstown, the first settlement it encounters. Flowing westwards it passes Ballyboy and Kilcormac before turning north to join the River Brosna near Ferbane. The Brosna flows west from the confluence to join the River Shannon at Shannon Harbour.

The Silver River is contained mostly within County Offaly but flows briefly within County Westmeath.
