Designed by Robert Trent Jones, Senior, and first opened for play in 1982, the Trent-Jones Cashen Course is Ballybunion's magnificent new course, located among amazingly high sand dunes at the mouth of the River Cashen. To say the course looks natural in its setting is to do it an injustice. The course flows with the land and uses the natural contours to full potential. This is a dateless golf course which after playing makes you ask yourself if you've ever played amid quite such surroundings. 40 miles north of Killarney.
