Why not try tobogganing in Verbier? The run from the top of Savoleyres to Tzoumaz is the longest run in Switzerland at 10km with a vertical decent of 850m and is superb fun whether you are 8 or 80. Skiers and snowboarders are not allowed on it but you do need to keep a watchful eye out.

Also, don’t forget to attach your leash because if you fall off (you will) the toboggan will run away by itself (it does) and you will never see it again (unless you come back and hunt for it in the summer).
