The paret is a wooden sledge handmade by the locals.
It was traditionally used by kids from Manigod (since 1900) to go to school on a snowy day.
Now, the paret which is still the same is used for fun.
During the winter season, you can try it in Manigod (usually at Merdassier on Wednesday late afertoon) or La Clusaz (Thursday evenings) depending on availability a free paret will be provided.
It is quite easy to use and find your balance, but I recommend you to wear ski clothes and a helmet.
