Starting from Grenoble and following the valley of Isere (upstream) you can reach Montmelian. If you turn north-west there, riding along Chartreuse mountain range, you reach a historical city of Chambery.

We decided to travel on the left side of Isere first, following some nice (but unpaved) roads for bikes and enjoying the river and the views of Belledonnes.

At Brignoud we passed a river and found some very nice agricultural zones with no cars and good roads. The views of Chartreuse are astonishing and you have some interesting places to visit on your way.

First of all, after passing Crolles you will notice Funiculaire de Saint-Hilaire - a tourist train climbing 700 meters and 83% slopes to reach Saint-Hilaire. It is even passing through a tunnel.

You may consider visiting some castles on your way. Usually they are inhabited and not widely open for public, but some are really old looking (like Chateau du Carre), some may be visited (check the gardens of Chateau du Touvet) and some provide a nice view of the surroundings (chateu at la Fayet).

The trip is mostly flat, but it is worth adding only 200 meters climb from le Touvet to la Flachere to visit last two of the mensioned castles and Fort Barraux.

To be honest, we did not find anything interesting in Fort Barraux, but it was partially closed due to works. As it is looking at the Isere valley, some nice views could be expected when all walking tarraces are open.

A nice Lac de St-Anore lake is worth mentioning, we found it to be a good place for a rest.

When you finally reach Chambery, do not miss the Fountain with Elefants, the Saint-Francois Cathedral, so called "Allees" of Chambery and last but not least - the castle of the duke of Savoie.
