We are going to to Basel in June. Is 3 days too long. It looks like there is a lot to see. All suggestions welcome
One full day is enough, the city center is very compact and it's easy to do a lot in a day.
Thats too much time. Switzerland's beauty lies not in its cities but in its land. You're much better spending just one day in Basel and then heading towards the Berner Oberland and spending your other two days there.
