Uetliberg Mountain

Uetliberg Mountain is 2,850 feet above sea level and offers fantastic panoramic views of Zurich, its lake, the Limmat Valley and the Alps. Several hiking and mountain biking trails lead up the mountain in the summer, many of which are converted into sledding runs in the winter. There is also a Planet Trail, which is a two-hour walk from Uetliberg to Felsenegg and takes you on a tour through a model of the solar system. The mountain is popular during the fall since the summit is above the fog that is usually present this time of year. 
The observation tower on the top of the mountain was built in 1990 to replace the old one from 1894. The tower is nearly 100 feet tall and also serves as a cell tower. There is also a hotel and a restaurant at the top of the mountain. 

Practical Info

Uetliberg Mountain can be reached by the steepest standard-line adhesion train in Europe from Zurich's main train station. Uetliberg is car-free, though you can drive to the Feldermoos parking lot at 12 Birmensdorferstrasse.
