Give someone a voucher for an unforgettable underwater experience. 

Explore the depths of different Swiss lakes on board our submarine. The underwater world has always captured the human imagination. Wrecks of sunken ships, aeroplanes and cars hold a particular fascination for us. They often lie at virtually unreachable depths and, in most cases, very little is known about them. 

Accompanied by experienced pilots, we sink silently to depths of up to 100 m. You’ll get to experience the feeling of weightlessness and see a variety of incredible sights up close. And if you’re a bit of a techie, the submarine’s many reliable displays, valves and instruments that tell us about depth, pressure and temperature are a fascinating attraction in themselves.
