To our disappointment, we didn't get a glimpse of the local celebrity, Fungie the Dolphin, but we got such a kick out of talking about him, that I thought I'd share the story.
In 1984, the lighthouse keeper started keeping tabs on a lone wild dolphin that frequented the Dingle harbor - rare for a dolphin in these waters. He was later declared an official resident and pilot for boats coming into the harbor, and developed from observer to playful companion to the fishermen, who named him Fungie.
There are boat tours that go to "look" for Fungie, while there are no gurantees, and you can even arrange to go diving with him. He apparantly welcomes human companionship, especially women. This web site will tell you all about him. Dingle Peninsula
