As observed on the map above, Ireland has dozens of coastal islands, including Achill, the country's largest. Others of significance include the Aran Islands to the southwest of Galway and Valentia Island just off the Iveragh Peninsula. Other peninsulas of note include the Beara and Dingle.
The River Shannon at 386 km (240 miles) long is Ireland's longest river. It widens into four loughs (lakes) along its route, including Lough Allen, Lough Bafin, Lough Derg and Lough Ree. Other inland loughs of note are the Conn, Corrib and Mask.
Besides the Shannon, additional rivers of size are the Barrow, Blackwater, Boyne, Finn, Lee, Liffey, Nore, Slaney and Suir.
