The citrus festival takes place in Zerfaliu every year, at the beginning of February, in order to set off the most important fruit of the area. The rich soil of Bennaxi, which had received river silt for centuries, turns out to be excellent for citrus growing. Therefore the fruits are juicy and tasty. The uncountable gardens, managed by small farmers, are rich of oranges, lemons, mandarins, clementines and grapefruits There are the most famous varieties, such as Tarocco, Vaniglia, Washington orange and Avana mandarin, but also the less famous but very tasty, such as the Sardinian orange. There are exotic fruits too, such as the kumquat mandarine.
During of the feast, organized by Pro Loco, many stands are opened in Trasfigurazione Square, where you can taste fruits, jams and other citrus dishes.
