Golf is the fourth-largest sport in the Netherlands, with almost 400,000 active members of the golf association NGF. The KLM Open is the most prestigious tournament in the Netherlands and is part of the European Tour, the highest professional golf circuit in Europe. Golf is being organized at three particularly beautiful clubs in Rotterdam, Cromstrijen, and Rhoon. The last two are located close to Rotterdam and their golf courses are situated in attractive natural surroundings. Joost Luiten is the best-known Dutch golfer – he is six times winner on the European Tour. Fun fact: on average, golfers live five years longer!
