If you can take in the french alps ralphie, its a truly awesome ride. I have ridden over col d isare twice now, en route to france from northern Italy, the roads around albertville are great too.Depends on how much time you have. Personally I would at least try to do it on way back. Take the autostrada across Italy and the turn off for col disare is from that . It wasnt hard to find, but a great ride. There are some fantastic bends running down to Lansleberg, where btw you can get fuel on your UK credit cards...very few filling stations about but this one took my card.Take a look at it on google maps.You can take a route back from albertville , through annecy , and over the Jura mountains too which is nice...and avoids going into switzerland and paying £30 for a vignette !
We stopped at chaumont before blasting back to calais, taking the slower scenic route over the Jura , but the motorway runs parallel, so you can take that if you need to make time.
cheers
