As this chap with a cool accent says, ‘it’s a proper golf hole.’  The Extreme 19th hole at the Legends Golf Course in South Africa has got to be the most incredible Par-3 golf hole in the world. The tee box is on the edge of a cliff, the green is in the shape of Africa set 400 meters below and there is no way I would ever finish this hole.    
3-time major champion Padraig Harrington actually managed to par the hole a few years back.  Any hole that you can fly to the tee-box is slightly intimidating in my books.
