The "Lötschberg", as we call the BLS railway here, is one of the most important feeder railways to the Upper Valais. The Lötschberg southern approach can be walked from Hohtenn to Naters. In Naters, the new "Lötschberger" trail leads to the Museum of the Swiss Guard and the fortress.
For the complete route of the Lötschberger from Hohtenn to Brig you should reckon with a walking time of around 8 hours.
The route can also be divided into several shorter stages.
