Bassecourt - La Combe - return

The title of this tour sounds like a railway connection - not entirely by chance. The route first takes us along the La Sorne to Berlincourt, then a fairly regular climb begins past Saulcy to the "Sur les Roches" height, from where we then descend steeply to La Combe, where we cross the railway line from/to Bassecourt. Shortly afterwards, we also cross the main road and then ride level back to the Jura crossing Les Rangiers.
On this ride at altitude, we have Le Tabeillon on our right in the valley below and the Sorne, which flows into the North Sea via the Birs and Rhine. On our left, the Doubs, coming from Pontalier, also flows towards the Rhine until it makes a sharp turn to the left at St. Ursanne and then flows via Besançon to the Rhône and thus into the Mediterranean. We are therefore on a European watershed, with the waters south of us flowing into the North Sea, and the waters north of us into the Mediterranean.
This terrain barrier is not only overcome by roads, but here also by two railway tunnels from Delémont into the Ajoie. We cross both tunnels shortly before La Caquerelle, but with a considerable difference in level. A tour that not only brings us closer to the beauties of the Franches Montagnes, but also impressively demonstrates what the folding of the earth's surface can do.
