I've done some hikes (snowshoeing hikes) some years ago with Bernard et Chantal et a naked canoeing trip with Chantal and her former husband. Of course, many of the participants but not all, were member of Apnel.
For several years, the Apnel was the most advanced association in the fight for the recognition of nudity. Now the French Naturism Federation is coming out of its sleep and is joining the Apnel positions.
