The flagship of the three courses at Killarney Golf Club, Killeen is firmly established as a traditional inland masterpiece, surrounded by the lakes of Killarney and some of Ireland's finest scenery.

The course is challenging to the best golfers with tight, tree-lined fairways, water featuring on nearly every hole and fast greens. At the Irish Open in 1991 winner Nick Faldo was one of only three players to finish under par.
