A 17.5-kilometre route starting from Commeny (Val d'Oise) and passing through Santeuil.For fans of naturist hiking (known as "randonue" to those in the know), certain sections of this route can be covered completely naked. Although encounters with other people are possible, the risk is minimal. Don't forget to bring something to cover yourself with (skirt, shorts, sarong, etc.), especially when passing through villages, so as not to shock anyone you might meet. Always be courteous and explain your naturist approach. This hike can of course be done fully clothed, with nudity being a bonus for randonue enthusiasts.The hike starts and ends in the village of Commeny in front of the church.
