As the ASO have been saying for a year, it's going to be all about the Alps, while there will be at most one Pyrenees stage that can actually do anything for the GC.
Yes the some of the route is known at this point.
Start in Passage du gois (flag not dropped till after it is crossed), stage 3 20km Les Essarts time trial (ill puke if another poster comes in thinking theyve discovered America and says "breaking news they will have a ttt in the Tour

")
4 days in Alps. Galabier and Alpe d Huez. Alpe likely climbed twice. 3 days in Pyranees.
1st week a day or 2 in Pyranees. I think theyll do the Tourmalet but no idea how far from the end.
I think others have more precise lists than my above spider diagram.
A few stages are yet to be known though.
