The Extreme 19th is the world's longest par 3, measuring 391 yards, and challengers can only access the tee by helicopter.Sat atop South Africa's Hanglip Mountain, at 400 metres tall it is also the globe's highest hole, meaning it takes almost 30 seconds for any tee shot to reach the Africa-shaped green below.Part of the Legend Golf Resort, situated in South Africa's Waterberg mountain range, the course has been designed by 18 of the globes top players, including Justin Rose and Retief Goosen.Irishman Padraig Harrington, the 2008 Open Champion, was the first person to make par on the hole but has since been joined by Morgan Freeman and many more.As there are no cameras or GPS used to track the flight of the golf ball, a spotter is employed to try and locate where it lands.(dailymail.co.uk)ANN.Az
