Hole 13 – 165 yards  

Looking at the yardage, players might immediately wonder what trick designer Cam Tyers devised for them on this seemingly innocuous hole. The answer can be found in the green, which is patterned after the Biarritz hole that initially was found in France and soon became a commonplace design feature of famed Golden Age architect CB Macdonald.

A Biarritz, or Biarritz green, is a green that features a deep gully bisecting its middle. The gully runs from side-to-side, and in the instance at Turnberry, it slides to the left. A Biarritz is especially challenging when the hole is cut on one side of the gully and your ball is sitting on the other side, requiring a long putt that must travel down the gully then up its other side to reach the hole. Some golfers choose to pitch over the gully rather than putt through it. The name "Biarritz" comes from the golf course in France where the first-known Biarritz was constructed, Biarritz Golf Club. The hole no longer exists, but CB Macdonald created a Biarritz green on the 12th hole at National Golf Links in New York.

Turnberry’s Biarritz is especially bold, with a narrow gully on the left giving way to a broader space on the right. Players missing the area where the green is pinned will have to use all of their creativity to recover.

“People may not recognize where the concept comes from,” designer Cam Tyers explains, “but they’ll remember the hole.”
