In 1941, a Swiss Air Force biplane crashed into the lake near Gersau during a training flight. The pilot lost his life in the accident, the gunner was able to save himself with a parachute and was rescued. The well-preserved wreck lies at a depth of around 200 metres. The machine gun, the cockpit where you can still see the control stick and the impressive wings are clearly recognisable. Pure excitement where you will experience a relic from times gone by up close. 

The meeting point for the diving trip is the Pier (Wehri bus stop) opposite the Pizzeria Al Porto, Gersau

Important: The submarine can cool down during the dive. It is recommended to bring warm clothing even in summer. 

The dive trips take place with a minimum of 3 passengers. As soon as the first slot at 10:00 am and then the second slot at 1:00 pm are filled with at least 3 passengers, the next third slot (4:00 pm) will open. If you are a group of 3 or more people, please contact us and we will open a slot for you.


The highlight of this submarine trip is the C-35 aircraft wreck
