Points of interest
Greifensee is a popular recreation area for biking and inline skating on the paved recreation path around the lake. Easy hiking trails follow the water and pass Greifensee castle before entering a nature preserve. There are well maintained bicycle roads all around the lake as well as on the banks of Aabach.
The lakeside is under UNESCO protection, and buildings are not allowed, resulting in reed bed and a rich fauna and flora: Around 400 plant species in the lake and 19 species in its tributaries. The nature reserves are important for the birds breeding there including more than 120 migratory species.
