In the heart of the city’s hustle, where concrete rules the landscape, Podoniftis winds its way — one of the last visible waterways of Athens. Despite its proximity to the city center, it remains surprisingly unknown to many.
A living oasis of biodiversity
Podoniftis is not just a historic waterway — it’s also a thriving ecosystem. In its clear waters, fish can often be seen gliding by. Frogs rest on the stones near the banks, while herons and other water birds are frequent visitors along the shore. On spring and summer nights, the air fills with the song of nightingales, and the tiny scops owl, known as “Gionis” in Greek, can be heard hooting in the dark.
Few other places in Athens offer such a close encounter with nature’s quiet spectacle. It’s a striking contrast — between the wild, green world of Podoniftis and the noisy, urban landscape that surrounds it.
The Expedition is growing – but it needs more wind in its sails.
For two years, Greek Expedition has explored and shared a different Greece – through stories, guides, and insights created without ads, sponsors, or paywalls.
Everything you see has been created only through personal funding, powered by curiosity and a passion for exploration, discovery, and sharing. That’s how we’ve stayed true to our course: in-depth, personal, and uncompromising in quality.
If you feel our work brings value, help us carry the Expedition further – toward new shores.

Origin and course
Podoniftis has its source on the southwestern slopes of Mount Penteli and flows through areas such as Patima, Vrilissia, Chalandri, and Filothei, before winding its way through Nea Ionia, Nea Filadelfia, and Patisia. Along its path, it has been shaped by both natural forces and human activity. Much of the stream has been covered over by urban development, but certain sections – especially between Nea Ionia and Ano Patisia – remain untouched, open, and accessible as walking trails.
Visiting Podoniftis feels like stepping into another world. Along its banks, you can hear the soft murmur of water that has flowed for thousands of years. It’s a place where time seems to stand still, where nature whispers its ancient stories to those who listen.
Near the intersection of Acharnon and Dekelias in Patisia, however, Podoniftis disappears from view once more, directed into an underground channel. From there, it continues toward Kifissos – the largest river in Attica – where it eventually merges as one of its many tributaries.
Kifissos flows both through and beneath the urban landscape of southwestern Athens, eventually emptying into the Bay of Faliro and the Saronic Gulf. During the 19th and 20th centuries, numerous industries and facilities were established along its banks, particularly in Athens’ heavy industrial zones, leading to severe pollution. Despite repeated cleanup efforts, Kifissos is still considered one of the most burdened rivers in the region. Much of its course today is flanked by major roadways dominated by asphalt, exhaust fumes, and concrete, rather than fresh air and green spaces.

Flooding and the threat of being led entirely underground
Historically, Podoniftis has been prone to flooding, especially during heavy rainfall. In 1994, Athens was hit by a severe flood in which Podoniftis overflowed its banks. Seventeen people lost their lives in the disaster, drawing attention to the stream’s risks and vulnerability.
To address these risks, additional stream sections have been covered, which, unfortunately, has resulted in the loss of many natural habitats. Today, voices call for the complete covering of Podoniftis to prevent future disasters. At the same time, several environmental organizations and local groups are fighting to preserve the stream’s open sections and its ecological value.
Administrative challenges hinder development
One reason the area around Podoniftis hasn’t been developed into a pleasant walking route, like the one along the Chalandri stream, is that it runs through four different municipalities: Athens, Nea Ionia, Nea Filadelfeia, and Nea Chalkidona. These municipalities have struggled to agree on coordinated measures to improve and maintain the area.
A stream with shifting moods
Podoniftis is not a stream that always behaves the same way. During dry periods, it flows quietly and gently, as if holding its breath. The water then moves slowly, clear and calm, almost meditative in its rhythm. But after heavy rains, it reveals a very different side.
The water can rise within just a few hours, rushing with a force that feels both alive and dangerous. The once gentle murmur turns into a roar, and the usually peaceful riverbed transforms into a thundering surge of churning, swirling water. In those moments, it becomes clear why debates over covering the stream and ensuring flood safety never fade from the local conversation. It’s as if Podoniftis wants to remind the city of its primal power, of the fact that it has been here long before the fleeting concrete.
A jungle in the heart of the city
Walking there in daylight is an experience in itself. Sunlight filters through the foliage, casting patterns of light and shadow along the banks. Small lizards bask on warm stones, while butterflies and dragonflies dance across the water’s surface. The soundscape is filled with birdsong, yet faint traffic noise in the distance reminds you just how close the city still is. The scent of damp earth and greenery is distinct, especially after rain, when the air feels heavy but fresh. It’s a place for rest, but also for discovery – especially for those who enjoy being immersed in nature.
In the first blue light of dawn, or during the reddish fade of dusk, Podoniftis takes on a tone all its own. The colors soften, contrasted by bursts of bird activity – swallows, blackbirds, and magpies shifting places in the trees. At times, mist drifts over the water, giving the landscape an almost cinematic quality. The light is gentle, and walking here often feels meditative.
Under the full moon, the still water takes on a silvery sheen, and shadows from the overgrown trees stretch across the stream like fleeting, dreamlike memories. The air grows cooler, birdsong fades, replaced by the soft calls of the scops owl, while the movement of the water becomes more pronounced, more present. It’s a place that invites contemplation — a nocturnal dialogue between human and nature, quiet and timeless in a city that otherwise never sleeps.
The name “Podoniftis” – an etymological riddle
The name “Podoniftis” is believed to derive from the Greek words pous (foot) and nipto (to wash), possibly meaning “the foot-washer.” Several theories exist: one suggests the stream was used by travelers or pilgrims to wash their feet. Another links the name to the area of Nea Ionia, which, before the arrival of refugees following the 1922 catastrophe, was known as Podaradika, a name that may have inspired the term Podoniftis
A visit worth the effort
For those who want to experience this hidden gem, the easiest way is to take the metro to Ano Patisia station and then walk west along Chalkidos Street (see map below). After a few hundred meters, a world of greenery, birdsong, and flowing water opens up — a gentle reminder of nature’s presence in the heart of the city.
Podoniftis is more than just a waterway; it is a living witness to the history of Attica and a symbol of nature’s resilience. Preserving and valuing this natural resource is essential for the ecological and cultural future of the entire region.
