Nice little town, but not really cyclist-friendly: the castle, a nice point of interest, is accessible only if you go to eat a lot (they say explicitly: "We are not a museum, a bar, a restaurant - here we have lunch, dinner and a snack"), the fountains are not drinkable, in short, the impression is that of being unwelcome guests. That said, visiting it in their face is a great satisfaction.

Famous for the fort which attracts many tourists all year round, but the historic center is also worth a visit. I recommend parking your car in Via Borgata Champs

Small village in the province of Turin, its most notable point of interest is the Fenestrelle fort, made up of three forts and seven redoubts. An archaeological site of great importance for local history. Even just a look from the outside is worth it; an imposing and fascinating place!

Of particular importance is the arch, which expresses well the value that Susa had for the Romans.
