Near to this tower, a river, the Vuachère, flows into the lake. Three rivers run through Lausanne. The Vuachère is the last to mainly flow freely, whereas the Flon and the Louve are largely canalized. The small verdant valleys of this river encourage animals of all sizes to roam right into the city. So it is not uncommon to encounter a fox or a hedgehog at nightfall.
Follow the “sentier du renard” (fox path), waymarked with fox tracks imprinted in the earth, as far as Avenue de Montchoisi.
