It would be no exaggeration to suggest that Marathon and the surrounding area is the whole of Greece in a nutshell.  The municipality of Marathon one of the largest in Attiki (222.17 sq km) with one of the longest coastlines (38 km).

Island-like sandy and rocky beaches, hills and mountains, thriving fields and austere hillsides, lakes, gorges, olive groves, vineyards, forests with remnants of the far and the near past scattered all around.

Highlights are the unique pine forest by the sea, the natural reserve of Shinias, ideal place for bird watching and the long sandy beach of the Marathon bay.
