The path, which leaves from the botanic garden and takes you to the alpine pastures at a high altitude, passes through a century-old spruce- pine forest, which transforms into a black alder wood, touches a knautia and goes past a larch forest and finishes opening into nardi and vegetation of flint rock.
This course offers excellent panoramic points which allow you to have a great view over most part of this spectacular valley.
This course which takes you as far as the alpine pastures is connected to the botanic garden as you can receive information regarding the flora and fauna and advice on their protection.
