Fastnacht starts Thursday and it is quite a sight.

There are parades on Thursday, Monday and Tuesday, it is a bit rauccus at night and if you are staying, I wouldn't recomend a hotel in the old town during the festival.

There's more to do in the summer for day trips, with boat trips, hiking, a trip up pilatus or just strolling around old town.

That's not to mean it's devoid of attractions in winter, there's the transport museum, the rosengart city walks and all manner of things.
