Please be aware that the stuff on books, maps and video was published in the stone ages. But it should still offer some important answers.
What I have found important:
- Plan all touring in the Alps as early as possible in the season:
Always finish by the mid of July if you travel on a no-prior-booking practice. This is when every normal Northern-European citizen start their summer holidays in Direction South. Be especially aware of July 14th in France: After this date you should feel lucky to find any accomodation at all.
- Stay away from sundays :
The traffic is often excessive (and it should be a good day to make some sleep anyway)
- Drive fast
- Do not drive too fast
- Speed does not necessarily kill
- Never panic
All advice are personal and critical. Not necessarily objective - but based on personal experience. No advice is paid for or influenced by any sponsor.
