Guided railway walk along the Lötschberg southern approach

Tracing the BLS mountain line – enjoy a beautiful and varied walk along the southern approach to the Lötschberg Tunnel from Hohtenn to Ausserberg, guided by an expert.

Der gut ausgebaute Wanderweg führt Sie von Hohtenn über Lidu, Brägji, Rarnerkumme bis nach Ausserberg. Unterwegs eröffnen sich Ihnen atemberaubende Ausblicke auf das Rhonetal. Ein weiterer Höhepunkt ist die Überquerung der imposanten Eisenbahnbrücke, das das Bietschtal überspannt.


The tour starts at the BLS Visitor Centre in Frutigen. First you will get a first impression of the tunnel system and how it works by means of a model. We then travel by minibus to the north portal and visit the intervention staircase. The journey continues to Mitholz and we immerse ourselves in the fascinating world of the Lötschberg Base Tunnel. This includes a tour of the Mitholz technical centre, the 1:1 scale test track and an exclusive look into the railway tunnel, where the trains rush closely in front of us at 200km/h.
