The Waterways: An Overview of the Shannon and Shannon-Erne
The Shannon originates in the Cuilcagh Mountains in County Cavan and flows for around 360 kilometers through central Ireland to its mouth near Limerick. For houseboats, the usable section mainly comprises the middle and upper reaches between Killaloe in the south and Carrick-on-Shannon in the north, supplemented by the large lakes Lough Derg and Lough Ree. The river is wide, flows gently, and in places is over a kilometer wide—a stretch that even beginners can handle with ease.
At Leitrim, the Shannon-Erne Waterway (formerly the Ballinamore-Ballyconnell Canal) branches off. This 63-kilometer connection was built in the 19th century, fell into disrepair for decades, and reopened in 1994 after extensive restoration. It runs through a chain of smaller lakes, including Lough Scur, Ballinamore, and Garadice Lough, to Upper Lough Erne near Belturbet and onward to Enniskillen in Northern Ireland. As a result, every continuous houseboat route on the Shannon in Ireland also crosses an internal UK border, which poses virtually no formalities for navigation itself but does raise questions regarding jurisdiction and legal matters.
