Lausanne is known for its rich architectural heritage, world-renowned educational and research institutions and magnificent panoramic views of Lake Geneva and the mountains. The seven-and-a-half-hour stage starts at Notre Dame Cathedral. The Gothic church, built of molasse, a soft sandstone, needed to be restored repeatedly since its completion.

Following a walk through the city, you reach the shores of Lake Geneva after about four kilometres. The beautiful sandy beach with shady trees invites the city's inhabitants to cool off in the summer. Along the lakeshore, you reach St.-Sulpice with its beautiful church. Continuing often directly on the water and shaded by old trees, you get to Morges. This small town was once an important trading centre. The harbour, constructed for this purpose at the end of the 17th century, is now home to yachts. The castle, built in 1286 by Louis of Savoy to protect the town, houses several museums today.

The path leads directly along or slightly above the shore through residential areas and vineyards to St-Prex and Buchillon. Next comes a short stretch along the banks of the Aubonne river to just before its mouth. In Perroy, a short climb leads to the village centre. Here you can enjoy fantastic views across the lake to the Savoy Alps. Almost half of the village is characterized by vineyards, which give the place its unique charm.

Now the route descends again to the shores of Lake Geneva, where the long stage ends in the pretty little town of Rolle.
