At the top of the summit, you have the opportunity to enter the Glacier Cave.

From the summit station of the Titlis Rotair cable car, you can reach the "Blue Heart" of the Titlis via a passageway. The corridor is 150 m long and leads 20 m below the surface of the glacier. The blue color is created by the refraction of light and at a constant temperature of minus 1.5 degrees, you are accompanied by the atmosphere of light and sound. Furthermore, the restaurant with sun terrace awaits all hungry visitors.
