A sand trap, also known as a bunker, is a common feature on golf courses designed to challenge players. It is a depression filled with sand, strategically placed near greens and fairways. The purpose of a sand trap is to add difficulty to the game, requiring golfers to use specific techniques to escape the sand and continue playing. When a golf ball lands in a sand trap, players must use a special club called a sand wedge to hit the ball out. Successful shots from a sand trap require skill and practice, as the sand can affect the ball's trajectory and distance. Proper technique is essential for navigating these obstacles effectively.
