Lake Promenade
Especially during summer, the lake is a beautiful place to spend the evening or the weekend. Starting from Bellevue, the boardwalk goes for about three kilometers along the lake towards Tiefenbrunnen. About halfway from Bellevue there is a meadow where you will find thousands of people on a sunny day.
Landesmuseum
The biggest Swiss history museum. You can also learn about the various traditions of the cantons comprising Switzerland.
Kunsthaus
One of the major Swiss art museums. Its specialities are modern sculpturer Giacometti and the surrealist 18th Century painter Fuseli, both Swiss. Entry is free to the main collection Wednesdays.
Langstrasse
Red light district of Zürich, with more drug dealers and police than usual, but interesting because even this most notorious spot in Switzerland is so clean and safe. The area is the most overtly multicultural spot of the town. In recent years, ateliers and stylish bars start to coexist side by side to the about 15 strip clubs.
Zoo
With the new Masoala Rainforest Hall, the Zoo is really worth a visit!
Le Corbusier House
A beautiful, modern villa planned by the famous Swiss architect. The visiting hours are very limited i.e. one day / week only in the summer and entry is expensive. Additionally, there is a legal battle between the city owner and the long time tenant.
Fraumünster
Old Gothic church former convent with window paintings made by Marc Chagall. No photos or videos allowed inside.
Grossmünster
Old Romanesque church, symbol of reformed Zurich, where reformer Huldrych Zwingli was appointed the people's priest in 1519. Go up the tower for a great view of Zurich, though the stairs can be quite small and steep.
Museum Buehrle
A rich private art collection worth visiting - although a little less rich after a recent brazen robbery in broad daylight. Call ahead, as it's currently not open during regular hours.
Jacob Coffee Museum
An original museum which describes the evolution of coffee and different aspects of the culture that has developed around it. The museum is closed for renovation until March 2013.
