I will be at a course in Bern from Monday 3 Sept until Thursday 6th [on which day I return to Geneva].
The schedule is quite intense until 6pm every day.
It would be nice to maximise leisure time in the evenings so any advise on what to do on Monday/Tues/Wed evening is appreciated.
Are 3 days needs to explore old Bern Town or [for example] is it worth taking a train trip to Thun in the evening? etc?
