SLALOM TRAILS are a type of ski trail that involve weaving between poles or gates. They are designed to test the agility and technical skills of skiers, as they must navigate the course quickly and accurately. The term SLALOM TRAILS is derived from the Norwegian word 'slalåm' which means 'sloping track'. These trails are often used in competitive skiing events, such as the Winter Olympics. The term ESSES (5 letters) refers to a type of slalom trail that involves a series of S-shaped turns.
