Been looking at (very loosely planning) an Alps trip for late (August/September) next year, I'm starting to see a nice route starting from Calais, 2 hours on the motorway through Belgium until you hit some nice roads around the Spa area, through Luxembourg then into Germany, 320 miles the first day (160 of that on motorways) + the euro crossing (I'm 30 miles from the Euro tunnel straight down the motorway so i don't count that bit!). Then down through Germany to the North Vosges, across to Baden-Baden and the legendary B500 and the Black Forest, stopping overnight in the forest (220 miles on day 2), and then it's only 170 miles to the Juan pass and the Swiss Alps
I've looked at avoiding Swiss motorways but in the end I think it's just easier to buy a Vignette! Kreee - I presume 'keine vignettenpflicht' which translates to 'no toll sticker' means you don't need the vignette for that motorway? I know the motorway sign is the same as the UK but only green, presumably the ones that don't say 'keine vignettenpflicht' you need a vignette sticker for?
So into the 'proper' alps on day 3, then finding a base camp for a couple of nights somewhere around Interlaken, then moving east along the alps, staying somewhere 2 nights (Lake como maybe), then allowing 3 days to get home (1 day from the alps to the Vosges mountains, 1 day from the Vosges to Luxembourg and then a short dash to Le tunnel) should make for a very decent 12 or so days with pretty easy days, not too much mileage, and a day off from riding would be easy to fit in too.
What's camping like in the Alps? I'm guessing there's not many campsites as come winter they'd have no-one staying there?
