4.5 Snowshoe Trails Design snowshoe trails using the same general criteria as easy hiking trails (Type I and II) or packed ski trails (Type III). Consider using backcountry hiking trails (Type III). that have moderate grades as designated snowshoe routes. Provide short trail loops in day use areas, for example 2-3 km. Separate snowshoe trails from other winter activities such as snowmobiling or cross country skiing. Avoid steep sustained grades for snowshoe routes.
