Handle moguls are a type of mogul skiing, which is a form of freestyle skiing. It involves skiing over a series of bumps or mounds of snow, known as moguls, while performing various tricks and maneuvers. The term 'handle moguls' refers to the use of SKI poles to help the skier navigate the moguls. Handle moguls require a great deal of skill and agility, as the skier must be able to maneuver around the moguls while maintaining balance and control.
