Just 30 kilometers from central Athens on the eastern slopes of Mount Parnitha, at an altitude of 600 meters, there is a small artificial lake that seems to belong in a fairytale. The landscape resembles the Alps and is not at all reminiscent of Athens. Lake Beletsi, named after the nearby peak of Mount Parnitha, was created by accident in the 1970s. When construction on the area’s infrastructures began, a torrent mound was closed off. Water began to accumulate in the region, creating the 5,000 square meter lake, which reaches 5 meters in depth. Even though it was created by accident, the lake is now an oasis near central Athens, where the capital’s residents and visitors can enjoy their day. The area is also home to many migratory birds, while the lake waters are often filled with swans and ducks. The lake area has slightly altered, with benches and playgrounds so that everyone can enjoy the scenery. Meanwhile, there are several hiking and biking trails for people who love to exercise. Nearby, there is the Greek Orthodox Church of the Holy Trinity, where hikers can enjoy a breathtaking view of Athens.
