Wife and I will be flying to Stuttgart, Germany beginning of August and will have 18 days before travelling to Paris. Purpose of trip is to visit the Black Forest especially Baden-Baden baths (Freiburg?) and if possible visit nearby parts of France (Strasbourg?) and Switzerland (Basel? Geneva? Bern? Zurich?).
We are unsure of how to budget our time and limited finances.
We will NOT have a car and will be reliant on public transportation. We’re fine staying in a simple guest house that has private bath and basic cooking arrangement.
Does it make sense to stay in Gengenbach or some other centralized town in the Black Forest and take day trips to places like Baden-Baden or Freiburg? We know Switzerland is pretty pricey but would like to go to at least one city for as little as 2 or 3 nights. Which would be worthwhile for experienced travelers who like to walk and bike a lot to get to know a place?
What itinerary would make sense for such a trip beginning in Stuttgart and ending in Paris?
ALL accommodation and other help most appreciated.
Thanks for any advice.
