About Lough Ree

Lough Ree is a large lake on the River Shannon in central Ireland, located on the midsection of Ireland’s principal river and notable for its many islands. The lake forms part of the Shannon navigation and is used for boating and angling.

The islands in the lake include early medieval monastic sites and ecclesiastical ruins, attracting visitors interested in history and archaeology as well as watersports. The lake is also a corridor for Shannon navigation between towns to the north and south.

Historically the islands and lake were important monastic and strategic sites during the early medieval period, with several island settlements and ecclesiastical foundations recorded in medieval sources.

Lough Ree lies in the central Shannon basin, north of Athlone, and spans parts of counties Longford, Roscommon and Westmeath.

  • Boating and fishing: The lake is popular for boating and coarse fishing, and several small marinas and slipways provide launch points for recreational users.
