La Lamberta Excavated in the molasse, they have 200 meters of galleries. The infantry work intended for the machine gun position is one of the scattered fortifications set up during the First World War to defend the Swiss Plateau. The construction of this infantry work took place between 1916 and 1917 and made it possible to protect the axis of Lake Morat. Today these caves have become a paradise for children for long games of hide-and-seek. https://www.j3l.ch/fr/P8751/lieux/sites-naturels/les-grottes-des-roches-grises-la-lamberta

Very pretty gorge to do with family, with friends. Accessible with an average physical level. So, nice little walk that could be followed by a navigation on Lake Bienne.

The Vaux stream is nestled among the trees of the Bernese Jura forest, and flows between Lignières and La Neuveville. From the Combe du Pilouvi trail, the view of the falls is breathtaking. It is a natural site full of magic, where witches once came to bathe in the sparkling water of the pools.
