The 115-km Grenzpfad Napfbergland is a long-distance hike which leads along the borders of the Cantons of Bern and Lucerne from Langenthal to the Brünig Pass in six stages. The route starts in Langenthal and then leads past the Baroque architecture of the former St. Urban Monastery. The trail then ascends to the Napf via Huttwil. After passing through Trubschachen, the route leads to the Wachthubel and then down into Marbach in the Canton of Lucerne, before ascending again to the Marbachegg. After descending to Kemmeribodenbad, the final ascent leads up to the Brienzer Rothorn.
The Grenzpfad Napfbergland was opened in 1998 and can be completed in five or six days. Various alternative starting points are also available.
