Some naturists don't hesitate to sunbathe on the banks of the Seine despite the Penal Code: " the sexual exhibition is forbidden in a place accessible to public view and it is punishable by a prison sentence”, plus a €15.000 fine.
For those who love open air, unauthorised sites are the only solution: a few green spaces on the banks of the Seine welcome the Parisian fanatics at their own risk.
Indeed the law considers that this practise is comparable to exhibitionism and punishes it severely. But it takes more to dissuade them.
