A fun, historic and practical short trip with the Polybahn in Zurich. It is located near the main station, over 130 years old, in fact a funicular railway in the center of the city, very loved by students, locals and visitors. In a few minutes, from the upper station, right by the ETH, close to the University of Zurich, you have beautiful great views over the old town and lake.
Have a beautiful day!
