The Bridge over the River Glatt :-)
Dübendorf has many bridges since the Glatt dividing the City into two parts. People from here love their river, beautiful for walking along in the summer.
Simple and easy spot reachable by any transport even tram or train; within Walking disatance from Dubendorf Trainstation
It's my third, doing this together with my kids.
Rather easy drive in by bicycle, very easy by foot. If you come by car, you will need to park your car in the area.
Please make sure you hide the container exactly at the same spot again.
