We are travelling on a 22 day pass. I'm wondering about jumping on and off at towns on our routes. I know some towns arent listed as possible destinations but might be between cities .Examples:
-Strasbourg to Colmar
Can we jump off at (or close to) Ribeauville/Riquewihr?
-Strasbourg to Koblenz
Will we have access between the towns along the Rhine river like Bacharach. Would be able to reach Cochem on the Mosel river?
-Interlaken
Could we use it do reach Lauterbrunnen , Grindewald or Thun on our way up to Bern?
Any tips would be great
