A toboggan is a simple sled traditionally used by children. It is also a traditional form of transport used by the Innu and Cree of northern Canada. In modern times, it is used on snow to carry one or more people (often children) down a hill or other slope for recreation. Designs vary from simple, traditional models to modern engineered composites. A toboggan differs from most sleds or sleighs in that it has no runners or skis (or only low ones) on the underside. The bottom of a toboggan rides directly on the snow. Some parks include designated toboggan hills where ordinary sleds are not allowed and which may include toboggan runs similar to bobsleigh courses.
