Depending on the time of year, you can watch different species of ducks resting in the nearby ponds. Ornithologists with binoculars or even a telescope are usually happy to give information! Parking for cars is available by the white willow tree just across the street!
Regarding the first comment: We are here at Lake Greifensee, not Lake Pfäffikersee.
Regarding the second comment: You can see the mountains in the distance when you look across the lake, so from the north bank of the lake rather than the south bank.
Sorry for my corrections (but there are generally a lot of mistakes and sloppiness in photos and comments in highlights).
