Sea Days of Jezera are the event held in Jezera from the beginning of July up to the final Big Game Fishing at the end of September. There are the manifestations of the cultural, sport and entertainment character held in the period twice or three times per week with the main idea „something for everybody“.

In the program there are the cultural and traditional elements (folklore, handmade things – e.g. how our folks used to live and have parties), classic music concerts, exhibitions. The sport part is based on indoor soccer tournament for children and adults, boat regattas, and the crown on the top is International competition in Big Game Fishing gathering about 60 teams from all over the world.

The entertainment program consists of children plays (children sing to us – a review of the little music talents) and all the others (fig fest, fishermen' fest – plays in our way – competition in the old sports, donkey races with the entertainment music). A significant part of the event is also the offer of the local food and drinks.
