This route to the Vercors offers the most variety of landscapes. Not only the Mercantour and the silent giants of Italy, but at the end we also enter the Vercors. This variety might offer us some new energy for the last days.
We definitely have to cycle for this one, it has the most kilometers of all the three routes. Negative about this route is the climbing of the unattractive Lautaret, and some might not be looking forward to return to the climbs of the Marmotte. 

With 3 roundtrips this stage tour has a good ratio between stop and go's.
