Switzerland. This is the Europe thread. I'd be working at ETH as a visiting scientist. You live in Zurich, AR? Tell me everything about cycling in Switzerland. I feel totally ignorant, though I've been in Switzerland once (1980). Or if that subject is too broad, how about:

(1) Is a bike useful/necessary to get around the city? Is walking and public transpo good enough if I didn't have a bike? Are city streets bike-friendly? Are there off-road bike paths in the city? Is bike theft a problem?

(2) Obvously there are lovely rides outside the city. Are there trips that combine train travel with biking?

(3) For overnight tours, are there adequate campgrounds, or are hotels/pensions/hostels a better choice?
