Hölloch Caves

A very special day off-site. As the start of a two day management workshop we went into the Hölloch caves, the largest cave system in Switzerland. Equipped with special "jumpsuits", gloves, rubber boots, helmets and headlamps, we climbed for 3 hours through tunnels and narrow aisles and finished with a cave raclette for lunch. A very unique but also physically demanding experience.
