Plan your gas supply conservatively around the rule of thirds, as the strong current can significantly extend your exit time. Parking and toilets are available at the site, but bring drysuits and appropriate thermal protection because the water stays cold year-round.
From the Gare du Day, take bus 685 to the Vallorbe, Grottes stop. Parking is available on site.
