Royal Portrush’s Dunluce golf course is famously the only golf course outside of mainland Britain to host the Open Championship, and after a 60 year drought, it was announced it would return in 2019, which was won by Irishman Shane Lowry. The combination of authentic, low-lying links land combining with the Irish dunes is prominently showcased here, with the golf course climaxing at the famous par 3, 16th, a do-or-die one-shot hole over a gully.
