Trail Reviews
A demanding course from the start having a very good physical condition, not within everyone's reach
Very beautiful landscape, and a very beautiful view of the lake
Unfortunately, some parts of the path were completely muddy after the long rain and therefore extremely slippery. Hence the short detour onto the asphalt path at the top.
