Clean Monday (Kathara Deftera) marks the beginning of Great Lent in Greece and the end of the Carnival season. In Pieria, the day is closely connected with Koulouma, kite flying, traditional Lenten food, outdoor gatherings and the arrival of spring.

Clean Monday, or Kathara Deftera, is the first day of Great Lent in the Greek Orthodox calendar. It follows the Carnival period and marks the beginning of the fasting journey towards Easter.
For many people in Greece, however, Clean Monday is also a day spent outdoors. Families and friends gather for Koulouma, share traditional Lenten food, fly kites and spend time together away from their everyday routines.
In Pieria, this combination of tradition, food, nature and community fits naturally into the landscape.
Koulouma is the traditional outdoor gathering associated with Clean Monday. Depending on the local community, celebrations can include shared food, music, dancing, children’s activities and kite flying.
Across Pieria, local communities organise Koulouma gatherings in different settings, from mountain villages to coastal areas.
The atmosphere is usually informal and communal. People come together to eat, talk, listen to music, spend time with family and friends and welcome the beginning of spring.
Food is one of the defining parts of Clean Monday.
The day traditionally follows the fasting practices of Great Lent, so the table is based on Lenten foods rather than meat and dairy.
Typical foods associated with Clean Monday include lagana, olives, legumes, vegetables, tahini-based dishes and seafood such as mussels, shrimp and other shellfish. Fasolada, a traditional Greek bean soup, is also commonly associated with the season.
In coastal Pieria, seafood can naturally become part of the table, while mountain communities may place greater emphasis on legumes, vegetables, bread and locally prepared dishes.
The important part is not a single menu. It is the idea of sharing food outdoors and beginning Lent together.
One of the most recognisable sights of Clean Monday in Greece is the sky filled with colourful kites.
Families head to open spaces where children and adults can fly kites and enjoy the first days of spring outdoors.
Pieria offers plenty of open landscapes for this tradition, from the coastline to countryside and mountain settings.
Rather than treating kite flying simply as an organised activity, it is best understood as part of the relaxed rhythm of Clean Monday: food, family, open air and time together.
One of the pleasures of spending Clean Monday in Pieria is the variety of landscapes within a relatively small region.
You can spend the morning in a mountain village, walk through the foothills of Mount Olympus, join a Koulouma gathering and later head towards the Aegean coast.
In spring, the landscape begins to change. Forests become greener, flowers appear and the longer days make outdoor exploration more inviting.
For visitors, Clean Monday can therefore become more than a single celebration. It can be a way to experience Pieria at the transition between winter and spring.
Village communities give Koulouma a particularly local character.
The 2024 local programme included Clean Monday gatherings in communities including Vrontou, Dion, Karitsa, Leptokarya, Litochoro, Neos Panteleimonas, Platamonas and Skotina.
The exact programme changes every year, but the common elements are familiar: people gathering outdoors, traditional food, music, dancing and activities for children.
For travellers, smaller village celebrations can also offer a different perspective on Pieria, away from the more familiar summer image of the region.
Vrontou is one of the mountain communities where Clean Monday has become an annual local celebration. The local mountaineering club organises its Koulouma gathering each year, bringing people together outdoors to share food, fly kites and enjoy the day with family and friends.
The 2024 celebration offered a good example of this community atmosphere, with traditional food, people gathering outdoors and the relaxed rhythm that makes Clean Monday different from the louder days of Carnival.

This short video captures the atmosphere of the day as it happened: people gathering outdoors, food being shared, conversations, movement and the simple energy of a local celebration.
It is also a reminder that traditions such as Koulouma are not only something to read about. They are part of the annual rhythm of the communities that keep them alive.
Clean Monday is not only a mountain experience.
The coastal communities of Pieria can offer a completely different setting, with the Aegean Sea providing an open horizon for outdoor gatherings and kite flying.
Places such as Leptokarya, Platamonas and Neoi Poroi can also be combined with a walk by the sea or a wider exploration of southern Pieria.
This contrast between mountain and coast is one of the region’s strengths: on the same day, you can experience a village celebration beneath Olympus and still reach the sea.
Clean Monday has a special place in the Greek calendar because it marks a transition.
The costumes, parades and louder celebrations of Apokries come to an end, and the more reflective period of Great Lent begins.
That does not make Clean Monday a sombre occasion. Quite the opposite: the day is traditionally associated with being outdoors, sharing food and spending time with others before the fasting period continues towards Easter.

Clean Monday does not have a fixed date. Its date changes every year because it is connected to the date of Orthodox Easter.
It always falls on a Monday and marks the beginning of Great Lent, following the final Sunday of the Carnival period.
If you are planning a trip around Clean Monday, check the local programme for the specific year, as individual municipalities, villages and cultural associations may organise their own Koulouma celebrations.
If you are visiting Pieria for Clean Monday, consider leaving some time for exploration rather than planning your entire day around one event.
Clean Monday, or Kathara Deftera, is the first day of Great Lent in the Greek Orthodox calendar. It follows Carnival and is traditionally celebrated with outdoor gatherings, Koulouma, Lenten food and kite flying.
Koulouma refers to the outdoor gatherings traditionally associated with Clean Monday. They can include food, music, dancing, kite flying and activities for children.

Yes. Depending on weather and local events, Clean Monday can be combined with walks, villages and other outdoor experiences around Mount Olympus. Check conditions before heading into mountain areas.
Summer is not the only season when Pieria comes alive.
On Clean Monday, the region moves outdoors: kites rise above the coast, families gather around simple Lenten food, villages organise Koulouma and the landscape begins its transition into spring.
It is a quieter kind of celebration than the big Carnival parades — but perhaps that is exactly the point.
Food, nature, tradition and people come together for one day before the rhythm of Great Lent begins.
From Carnival traditions and Koulouma to Mount Olympus, mountain villages, archaeological sites and the Aegean coast, Pieria offers many ways to experience local life beyond the summer season.
