About
The River Shannon is the longest river in Ireland, with a total length of 386 km. It rises at a place known as the Shannon pot, near Dowra, in the Cavan Mountains but the various tributaries and bogs along the spine of Ireland also filter into it and together have forged this great river. The Shannon is a natural barrier which divides the west of Ireland from the southern and eastern provinces of Munster and Leinster.
