An island in the middle of a very large lake. The lake is connected to several other lakes called the Chain O'Lakes. It is open in the summer. I believe they still have boat races. I recommend taking the ferry from Port of Blarney. There are a lot of drunks in their boats and it can get crazy out there. Everyone is overserved and the music is great and you are in the hot sun. Not a lot of shade. If you have a boat, you can dock it. It is trashy, I warn you. A lot of people come out of the woodwork. But honestly, if you are with a group of friends, you will have the time of your life. If you are looking to get lucky...I would think twice.
