The River Shannon is the longest river in Ireland and crosses most of the island from north to south. It rises in County Cavan in the north and eventually flows into the Shannon Estuary in the west, which leads to the Atlantic Ocean. The river has a length of about 386 kilometers.

The Shannon is not only scenically impressive, but also plays an important role in Irish history, culture and economy. Along its banks there are numerous historical sites, castles and towns that can look back on a long past. The river is also a major transportation route and is used for recreational activities such as boating, fishing and water sports.

The Shannon and its surrounding areas also provide rich habitat for a variety of plant and animal species, including rare bird species and fish stocks. Overall, the Shannon is an important natural and cultural heritage site in Ireland.
