Zoo Zürich
This is one of Europe's outstanding zoos, with more than 1,500 animals, including Asian elephants, black rhinos, seals, and big cats. Two of the more unusual attractions are a huge dome stocked with flora and small free-range fauna you might encounter in a jungle in Madagascar, including lemurs and the endangered Bernier's teal; and the elephant park, Kaeng Krachan, which allows you to see the elephants swim underwater. Set in a tree-filled park, the zoo is just east of the city center and easily reached by Trams 5 and 6.
