Par 70, yardage 6,976. Long regarded as one of the finest courses in the world, the Ailsa came to international prominence with the famous duel between Jack Nicklaus and Tom Watson over the four days of the 1977 Open. Polls now regularly acknowledge the Ailsa as one of Britain's top three courses, confirmation that gives it eminence worlwide, with regular rankings within the world's top 20 courses. Perhaps the ninth hole is Turnberry's trademark, the remote tee set on a rocky promontory on the edge of the sea, the drive across the corner of the bay and a glimpse of the site of Bruce's Castle. The narrow path to the tee and the tee shot itself are not recommended to those of a nervous disposition.
