The feast of Ayios Yeoryios, the island's patron saint, is observed with a procession of the saint's icon around the island. Streets are strewn with flowers for the occasion, while the procession's route is followed, from sea, by fishing boats until its return to the church. Services are followed by a communal meal of boiled beef, which evolves into a traditional glendi with singing and dancing in the tavernas.
Holy Week and Easter are special as they involve the entire island. On Good Friday, the island is illuminated by candles and the resurrection service at midnight on Saturday is followed by fireworks.
The Fisherman's Feast on the last Saturday of June takes place in the streets and square. Tavernas are closed so that everyone can join in a communal meal of fresh fish and fish dishes, washed down with wine and accompanied by music and dancing.
The feast of Profitis Ilias on July 20 is also observed with a glendi-food, wine, music, and dancing.
The Dormition of the Virgin on August 15 is observed with services at the church of Panayia at Kato Koufonisi, where islanders are transported by fishing boat. Services are followed by a fish fry (or sometimes a meal or lamb or goat). Fishing boats race during the return; winners and losers trade toasts as the paniyiri continues in the evening with music and dancing.
