From St. Saphorin to Lutry there is an official hiking trail on the lower part of the slope, which is also a cycle path and leads partly all the way down to Lake Geneva (this section) and there is also an official hiking trail at the very top by the terraces that leads right to the railway line. The upper hiking trail is not really suitable for cyclists in the area of the railway line, neither for strollers nor for mountain bikes 🤷. For the lower hiking trail, I recommend hiking the area between Epesses train station and the village of Cully directly by the lake and not staying on the hiking trail a little higher up. The lake promenade is a welcome change.
The two hiking trails at completely different heights are ideal for a circular hike and can be reached at any time via the many winegrowers' roads running across them, depending on the desired length of the tour. The most common grape variety is "Chasselas", which I really like 😋😊.
