You will get to see the hidden gems of Zurich, over the course of this 2-hour long walk. The first destination is a secret tunnel from the Middle Ages, which lies behind an almost invisible and locked door. It’s so inconspicuous that most people who have been living in Zurich for years don't even notice or know about it.
You will be visiting the only remnants of the city wall from the 13th Century with the city’s first water pipes, which are hidden and locked in the basement of a modern building.
Your adventure will continue through a hidden door on the ground of a famous park area, where thousands of people pass by every day without knowing about this door. You will climb down to find the historical walls of a Roman Fort and of the Royal Palace from the Middle Ages!
