The 10 most bizarre golf courses in the world

You'd be hard-pushed to call golf an extreme sport. It is a low-risk game played at a leisurely pace in mostly scenic, but ultimately ordinary, locales.

Emphasis on most, because in various pockets around the world - and in one instance, outside it - golf is taken to extremes.

Across these venues, the familiar rules of course design have been shredded; dress codes are exclusively nude, tee boxes require a helicopter journey to access, fairways sit on the rims of active volcanic craters, and water hazards are home to sharks and alligators.

"The ardent golfer would play Mount Everest if somebody put a flagstick on top," celebrated golf course designer Pete Dye once said. The following courses are a love-letter to that ethos.

Generally, golfers like it to be quiet when they swing. At professional events, stewards will hold up signs to instruct nearby spectators to be silent.

Unsurprising then, that no Tour events are hosted at Kantarat Golf Course in Bangkok, where players must periodically tune out the deafening roar of passenger airplanes touching down and taking off either side of them.
