Mount Parnitha (Greek: Πάρνηθα) is a densely forested mountain range north of Athens, the highest on the peninsula of Attica, with an elevation of 1,413 meters
Much of the mountain is designated a national park, and is a protected habitat for wildfowl, first created in 1961.
The name of the mountain dates back to ancient times, when it was under the ancient demes of Acharnae and Decelea.
