a cottage industry has arisen around trips to see a local legend, Fungie the dolphin. Boats go out daily to try to tempt this wild dolphin to intereact with the wetsuit clad tourists. The boat ride sounds okay to me (but I think I'd prefer a boat trip out to the Blaskets). The environmentally aware part of me cringes to think of the exploitation of a wild creature.
Fun Alternatives: take a boat trip to any of the islands around Ireland - the Blaskets here on Dingle; Skellig on Ring of Kerry are local alternatives.
