If you are touring in the Killarney area near Ross Castle, and have the time, I recommend rowing a boat over the lake to Innisfallen. Innisfallen island is over the lake a bit from the castle, and my valiant husband braved the wind chopped lake waves and rowed us over.
Innisfallen was the site of a monastery established in the 7th Century; people say that King Brian Boru studied there. If you go, you will see the remains of a 11th or 12th century priory and church. But mostly, what you will feel and see is peace, quiet, history, and the remembrance of past saints’ prayers. Slainte, Lisa
