While Old Tom Morris lays claim to being the original designer at Lahinch, it is Alister Mackenzie—architect of Augusta National, Cypress Point, Pasatiempo, and Royal Melbourne—who deserves a fair share of credit for the beautiful golf course we play today. In 1927, he relocated quite a few greens, building his signature, flamboyant contouring. Views across the bay and stunning, rolling links golf is the name of the game at Lahinch, regularly included in World Top 50 rankings, and among the single best golf courses in Ireland. It is a cliché to call every golf course a must-see, but Lahinch may only be second to one or two others on a trip to Ireland and Northern Ireland.
