Definition: A biarritz, or biarritz green, is a green that features a deep gully bisecting its middle. The gully, which is manicured the same as the rest of the green, usually runs from side-to-side, but sometimes runs from front to back. 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" come from the golf course in France where the first-known biarritz was constructed, Biarritz Golf Club. The club's La Phare Course is home to the original biarritz.
