Aside from Alpe d'Huez's 21 hairpin bends, what else do you know about Isère?

Tour de France: You may know about the 21 hairpin bends on the road up to Alpe d'Huez in Isère. But what else do you know about this French department that's also the third-largest ski region in France?

The Tour de France 2020 enters into Isère on Monday 14 September for 3 days, leaving its main city of Grenoble on Wednesday 16 September.

So for those who want to know a little more about this mountainous area, here's a round-up I wrote as a guest post on Mary Anne's France.
