Lake Beletsi is a small artificial lake, created by accident in the mid-1970s during the construction works for a road that would connect Agio Mercourio with Afidnes. The natural flow of spring waters in that area and the runoff from rainwater were blocked, forming a 5,000 square-meter lake. At an altitude of 600 meters above sea level, just 30 kilometers from central Athens on the eastern slopes of Mount Parnitha, the lake is an oasis for the capital’s residents. It is named after the nearby peak of Mount Parnitha but is also known as Kithara (“Guitar”) because of its shape.
Many migratory birds rest on the shores, while carp, eels and turtles swim in its waters where you can also see swans and ducks. A recreation area has been formed in the surrounding area with benches and playgrounds. There are also several hiking and biking trails for people who love to exercise. Lake Beletsi is a very popular nature destination, ideal for sport activities, picnic, hiking, biking or just capturing some great photos. Nearby, stands the small chapel of Agia Triada with panoramic view of Athens and village Sfendali, with the beautiful train station and the tavern that is on the back side. Located at the entrance of the village Ippokrateios Poleiteia, the lake can be accessed easily from Varibombi or Afidnes.
