Lets start off with directions!
First here are three alternate ways to get to the Ring if travelling from Calais that I tinkered around with using the really excellent ViaMichelin route planning guide.
Dunkirk is just 30 min down the road so these apply to people arriving leaving from Dunkirk too.
It might be useful to pick one of these, familiarize yourself with it, and defintely print it out to bring with you!
It might be an idea to expand some of the salient map mini-segments.
(Each stage has a "display map" link which adds a neat little mini map which can be printed out.)
If you have a Sat Nav, it is very useful to examine its chosen route to the Ring and get the ViaMichelin website to print out the steps as a backup in case your Sat Nav/PDA stops working in low cloud/fog/electrical issue whatever.
To avoid clutter I haven't given links for the return journey, but the site is so easy to use I suggest you go ahead and also print out the steps for the return home.
1) Link for directions from Calais to the village of Nurburg following the "short cut" via Eupen recommended on Ben Lovejoys site.
You pass by the main public entrance to the ring before you get to Nurburg - which is actually a village inside the Ring itself.
Nurburg is where the Am Tiergarten hotel that the AlfaOwner group are staying is located.
Ben Lovejoys site also provides a detailed picture guide to this route, and I have added
2) Personally I found the above route with the suggested short cut via Eupen very slow, with some badly surfaced roads (albeit scenic ones) and would suggest staying on the motorways much longer as suggested by the via Michelin site, which also thinks it is quicker :
The first portion of Ben Lovejoys picture guide above applies to this route too.
3) A route through Charleroi which my own Sat Nav seems particularly keen I go!
It seems simple enough with staying on the E42 for 380km.
NB: Obviously stay on the E42 and don't go into Charleroi city centre :-)
I just added Charleroi as a waypoint here to force the Via Michelin to take the E42 route instead of the option 2) above.
I'm meetin up with Peter and Vamos a few days before the AO trip itself so won't be travelling in any convoy from the UK.
If people are travelling in convoy in the UK, and are using Sat Navs just check that the two Sat Navs have chosen the same route - probably a good idea to nominate a lead car or have some signal to indicate "my sat nav is fecked, I'm following you!"
