If you ever happen to get a game on one of the following courses, pinch yourself. In the world of the exclusive golf club, not even billionaires and champion golfers get a look in without knowing a member.

PINE VALLEY GC

Camden County, New Jersey, USA

Pine Valley is generally regarded as the best course in America and arguably the world.

It was designed by George Arthur Crump who died before the course was completed so this remains his only work.

It is a highly exclusive club with an almost hidden entrance, which is via a dirt parking lot and railroad crossing. Pine Valley has a male-only membership and you must be invited by the board of directors to join. There are approximately 1,300 Pine Valley members spread across the world and their names are a tightly held secret.

It is understood that two members were once expelled for charging guests $10,000 for a round.
