France
The cathedral of Our Lady looks rather plain from the outside as it doesn't have the spires or the gothic façade which make it resemble a cathedral, but don't be put off by this - inside there are magnificent chapels with colourful and striking paintings and altars.
Cathedrale de Notre Dame is a 20 min walk from the train station
One thing that you must do is take the speedy "Bulles" from Grenoble city centre up to La Bastille, in just 20 minutes it whisks you high above the Isere river and the La Tronche district of Grenoble, it's the first city centre cable car to be constructed in the world.
Just follow the "Telepherique" signs from the train station - just look out for the cables above the Isere river - you can't miss them.
A return trip costs €5,75 and entry to La Bastille and the 1968 Olympics exhibition is free.
