There are some good attractions for children in Zurich.  The Zoological Garden on the eastern side of the city is excellent. It's compact, tree-filled and has a great collection of animals. The fascinating Madagascar pavilion and elephant  house are worth a look.

The fortress-like Swiss National Museum will appeal to older children. There are interesting prehistoric and Roman artifacts, weapons collection and the elaborate battle constructions of different conflicts, with small soldier figures.

Other things of interest are Zurich Toy Museum and huge toy store on Bahnhofstrasse called Franz Carl Weber. A walk along Zurich's historical quays and a boat ride on Lake Zurich will keep you and your kids happy. Alpamare, a huge water park, is only a 30-minute ride from Zurich, and is the best way to spend a pleasant summer day.
