Guided group tour

Ferden emergency stop area

Take a look inside the Lötschberg Base Tunnel

If you would like to experience a tour of the Lötschberg Base Tunnel with a group, we have the right offer for you. During this guided tour, you and your guests will learn a lot of interesting facts about the third-longest tunnel in Europe, such as how the fresh air supply is regulated in the tunnel or how passenger evacuation is organized in case of an emergency.

Private group tours are possible at any time by appointment.


The tour begins at the BLS visitor centre in Frutigen. First, you’ll get an initial impression of the tunnel system and how it works with the help of a model. We then take a minibus through the tunnel carcass from Mitholz to the Valais and visit the emergency stopping point and the ventilation centre in Ferden. On the way back, we make a stop in Mitholz to visit one of the 12 technical centres. This is where all the infrastructure is located, providing the power supply, radio, signal boxes and air conditioning.
