As you can see here (
http://www.deutsche-jakobswege.de/wege-uebersicht.html), Germany is covered by a spiderweb of
Jakobsweg routes. The Germans love to hike, so these are well-built, well-marked (in the German fashion, which is not as frequent as the French and certainly not as frequently as in Spain) routes through forests and fields, going from one town center square in front of the church to the next. There are route guides with maps, elevation profiles, and some lodging suggestions available for all these routes from Conrad-Stein (
https://www.conrad-stein-verlag.de/p/verlag/programm_jakob.html) in the famous little yellow books that are available in every bookstore in German-speaking lands (including Amazon.de). Lodging and logistics support is richly available in every town. The lodging rates are more expensive than in France, but it includes an enormous breakfast of cold meats and cheese and breads and usually soft-boiled eggs - that often has enough for lunch as well.
In Switzerland, the route is called the
Via Jacobi. The scenery in eastern Switzerland is not to be missed. The routes are also well-built and marked, and covered in the Conrad-Stein guidebooks. The routing dodges the towns, however, so one must leave the route for overnight lodging and logistics. The Swiss offer the full gamut of price options, from sleeping on straw in old dairy barns, to glamorous resort hotels.
I've walked from Prague, across Bavaria from Tillyschantz to Lake Konstanz, and across Switzerland through Einsiedeln to Geneva. Details of staging and lodgings in my blog, of course.
