At Ludgrove school, where he went until he was 13, William was rugby and hockey team captain and represented the school at cross-country running.
He also won the school prize for clay pigeon shooting in 1994.
Although Wills is a good golfer, it was not always just the ball that got hit! In 1991, he had to have an operation after being hit on the forehead with a golf club.
Prince William made a splash in 2004 when he was picked to play for the Scottish universities' water polo team in a national tournament.
William also loves rugby, motorbike riding and skiing.
