The Blauenberg mountain range is a forested mountain ridge in northwestern Switzerland and lies in the cantons of Basel-Landschaft and Solothurn. The path on the ridge allows some impressive views of the Birsig and Birstal valleys in the north and the Laufental valley and the Jura heights in the south.

The beech, which predominates at this altitude (approx. 837 m above sea level), grows vertically and straight upwards on the deep soils. This is why the forest looks like a columnar hall. Due to its rock, consisting mostly of light-coloured limestone, it is possible to discover many fossils of marine animals such as mussel shells, snails, ammonites, belemnites, corals and sea urchins during hikes on the Blauenberg.

A visit to the Blauenberg is a good opportunity to make a detour to the Blauenweide, where you can enjoy a beautiful view to the south into the Laufen Basin and the High Jura.


From Pfeffingen you first pass through the settlement and later through the forest on the route to the Pfeffinger Bergmatten. The path through the high pastures leads to the Blattenpass (Blaue Blatte). At the crossroads near the edge of the forest, the steeply ascending hiking trail to the Blauenkamm is signposted. Gradually the path rises more gently and stays in the middle of the ridge. In former times, this path formed the border between the cantons of Bern and Basel-Landschaft. That is why the characteristic bear is still present on all the boundary stones. From the hiking trail on the ridge, there are various descent options to Ettingen, Blauen or Hofstetten-Flüh. If you can spare a whole day, you can hike to the Challpass or Metzerlen/ Mariastein, where there is a connection to public transport.


Again and again the trail is lined with small barbecue and camp fire sites as well as picnic areas. The Restaurant Bergmatten above Hofstetten-Flüh also offers a small menu and snacks.
