This is already the second post about Uetliberg in the hiking category. Since its so easy to access, close to the city and able to present some beautiful views its already one of my Zürich favorites.
To get to the peak, take the S12 for gleis 2 at HB. It departs 05 and 35 each hour. The plan we had yesterday was to hike 2-3 hours in total with a lunch break. This was accomplished and we decided to end the hike in Thalwil which was perfect to get back to Zürich Enge in only 10 minutes.
Now is really the perfect hiking season for this hight and its just perfect for a sunday. No need to get up early to travel hours to get up in the mountains and easy to get home.
