A festival in the Bauges run by Les Fondus de Slack, the slackline commission of the Club Alpin Français of Chambéry. Days are free, with slackline initiations, circus arts, mountain sports and highline demonstrations; evenings bring an aerial show, a film, open mic, a slackline show, a concert, a fire show and a DJ, with camping and meals on site.
The public can try slackline; the highlines are demonstrations only.
