Lough Key Castle Island Loop

Part of the Shannon and managed by Waterways Ireland this clean, tree lined lake has one of the countries most unique castles locations standing proud in the middle of our swim.  The aptly name 'Castle Island' gets lapped by our 1.5km course while the 750m swimmers will cruise by its front door.

Remember if you are feeling fit you can swim both of our distances on the day for the one entry.  

Lough Key (irish: loch Cè) the "Jewel of the west" it derives its name from Ce which was the druid of Nuadha of the silver arm. According to legend Nuadha of the silver arm was the king of the ancient Tuath de Danann which means the people of Danu.
