Discover Grellingen: Chessiloch, Karst and Culture

If you want to shape your stay around specific interests, Grellingen offers two distinct highlights: military history at Chessiloch and karst landscapes with caves and water. There are also individual local sights and routes whose starting or ending points can be specified. This lets you consider cultural history, landscape and route choices separately.

Cultural history at Chessiloch

The “Chessiloch” coat-of-arms rock formation is considered unique in Switzerland and is one of the country’s most significant military history monuments. During the mobilisation period, around 60 emblems were painted or carved into the rock there. Since its restoration in 1934, the annual “Chessilochschiessen” shooting event has been held in remembrance of guard duty during the two World Wars. Chessiloch thus brings together two periods: the emblems created during the mobilisation period and an annual commemorative tradition.

Other local landmarks can also be placed in their historical context. St. Laurentius Church in Grellingen was consecrated on 10 August 1836. The municipality also lists Glögglifels among the local sights. This takes you beyond the military history site to other named places in Grellingen.

Karst landscape, caves and stream bed

The karst trail runs between Zwingen and Grellingen, passing steep rock faces, clayey caves and clear springs. More than a dozen information panels in Brislachallmet and Kaltbrunnental provide information about the underground, the fragile cave ecosystem, its formation and its light-shy inhabitants. Interpretive features may change over time.

The “Chessiloch & Chaltbrunnental” hike starts at Grellingen railway station. One route from there follows the Birs to Chessiloch; the first caves, Heidenküche and Kohlerhöhle, are not far from there. A hike through the picturesque Chaltbrunnental follows the stream bed. These descriptions emphasise different aspects: one follows the river to Chessiloch and the caves, while the other runs through the valley alongside the stream.

The Karst Trail Association offers guided tours led by specially trained trail guides. If you would like to include a guided tour in your plans, check its availability before your trip.

Tours and getting your bearings

The BLKB-Bänkli hike from Hochwald to Grellingen is listed as 15.56 kilometres long and taking 4.83 hours. Its route description leads from Nenzlingen via Felsenagger down to Grellingen; the hike can also be completed in the opposite direction. The distance and duration give you specific information for planning this tour.

Another option is an e-bike cultural tour along the Birs to Grellingen via Veloland route 23. The activities described therefore already differ in their mode of transport and route information: the Bänkli hike lists its distance and duration, while the e-bike tour is described as following the Birs and Veloland route.

The karst trail can be reached by Regio-S-Bahn to Zwingen; the return journey by public transport is from Grellingen. Route information and public transport connections may change. Check the current route description and timetable before your tour; if you are planning a guided tour, confirm its availability.
