very interesting story, the secret tunnel, in case of emergency, if it had been necessary in case of war, to blow up the Devil's Bridge, then this would have been the connection

Be careful at the entrance where you go from the rubber mat to the ice. I almost fell. I thought the frozen stuffed animals were funny. Nice atmosphere with the blue twilight.

The tunnel offers an interesting route to the station and at the entrance you can see an instrument used to measure tunnel construction.

Glacier Grotto, Titlis It feels like you are traveling back in time: in the turquoise-blue twilight of the glacier grotto, where the ice, which is up to 5000 years old, freezes the air we breathe into clouds of mist, the mighty heart of the glacier beats. On the 150-meter-long path 10 meters below the surface, you can feel it under your feet and touch it with your hands. An experience that will touch you in a profound way.

The path in the Aa Gorge leads through a small natural tunnel, nothing spectacular, but very beautiful.

The 150 meter long corridor of the grotto takes you ten meters deep under the surface of the glacier. The exploration tour through the glacier grotto is really cool. The temperature in the grotto is constantly at a chilly -1.5 degrees Celsius. You can easily reach the grotto via a corridor from the first level of the TITLIS mountain station. For free
