This short discovery trail dotted with information panels leads up a steep slope to the Salève ridge. It runs through a range of different mountain environments.
After crossing the village of Vovray-en-Bornes and passing a chapel, the path continues on sandstone soil through a forest full of conifers and blueberry bushes. Beyond that lie the mountain pastures. Up at the Plan observation platform, there is a superb panoramic view and a viewing table. The return journey again runs through the woods, and the hamlet of Rogin. The information panels along the way show how the pastures and forests are used and have changed over the years.
