You will find the Basilica on top of a mountain right outside Torino, a 15 minute drive. You must have a car or some other way of transportation to get there, I would not walk up there my self. The climb is about 550 meters.
The view is stunning. For 3 euros, one person also gets to go to the top of the Basilica to have a view of Torino completely rid of trees and masts in the way, the view is amazing.
I am slightly ashamed to have to say that the rest of the church is however average. We have seen so many stunning and amazing cathedrals and churches in Italy, that this is just one more small-sized building. It is very beautiful though compared to most churches in the rest of Europe, so together with the view, this becomes a decent and worthwhile attraction in Torino.
