Rather technical trail on the heights of La Baie which gives a breathtaking view of the Saguenay Fjord and the Baie des Ha! Ha!

Alternation of rocky viewpoints, forests and coves on the edge of the fjord.

This route is based on the SwitzerlandMobility official footpaths. It is classified as a local route (3 numbers), and is very well maked with the green on yellow sign "138 - Sentier nature Grand Lausanne". 

This routes goes around the town of Lausanne in its outskirts, following the greenest parts of greater Lausanne. 

This the official description from the SwitzerlandMobility website [https://schweizmobil.ch/en/hiking-in-switzerland/route-138] :
