One of the most scenic parts of our trip was cycling from Valensole to Grasse through the Gorges du Verdon. This was a beautiful and sceneic ride, but a long one: 150km, with 2,500m of vertical climb, following our first day of 130km from Aix. Still, we got to stay in a castle in Valensole which was pretty cool.
Nonetheless, it made for a long day and as a result of a couple of wrong turns we finished in the dark coming into Grasse. It was somewhat terrifying to be coming down steep mountain roads in the dark, but drivers are very good about watching for cyclists and we were grateful when we got near town and had streetlights to provide visibility.
