Pete, if your going to Monaco, you absolutely CANNOT miss driving through the Verdun Gorge.

Trust me, just do it! The southern end of the gorge is less than 100 miles from Monaco.
I did it last year, across the Alps, through Italy & back through Monaco, and north back to Dunkirk. I will go as far as to say, that it is the single best road I have EVER driven on. You must stop in a town called Digne Les Bain too. Beautiful.
With regard to the Pyrenees bit, Chris (GBMUD) has kindly offered me a loan of those books

mentioned earlier in this thread too. I think with those books & some maps between us & a dictionary, we can sniff out the best tracks/routes.
I will probably get a ferry on either the 20th or 21st, and will get to the mountains in a day. Driven in the west of France before, so I dont need to hang around.
Can you let me know what maps you end up with tomorrow & will be working off please?
Martin
