We took the train through the tunnel to Gänsbrunnen, once a major railway waypoint and still a well-used route through the Jura
and from there took a bus back to Welschenrohr. From there we walked steeply up through open woodland
to the plateau at the top of Weissenstein. On the way, Sue discovered some interesting fossils, as well as cracks
in the limestone emitting cool air currents. At the top, the hotel was being rebuilt,
and the farm restaurant was expensive and fully booked, so we had excellent sausage and chips at the
cable car snack bar! The way down was very unpleasant - steep tracks with loose gravel, mud and stones.
We decided to take a detour to look at the dinosaur tracks on the face of a quarry,
much to be recommended, and then took a bus back to Solothurn.
