Many towns, cities or villages celebrate this first Summer Fiesta. All the celebrations share some things in common, yet each also has its peculiarity.

In cities and towns, particularly those close to the sea, the celebration is very important. Lalín, in Galicia, celebrates O Corpiño, during which people touch an image to botar fora o meigallo, to take out bad things. In Alicante's Fogueres de Sant Joan, two hundreds bonfires burn all over the city during the night. In Palamós and Roses (Girona), fireworks and bonfires are made on the beach, while in Las Palmas de Gran Canaria, the people build bonfires of waste products, and after the burn, bathe in the sea, which they have filled with fruits and flowers.

Bonfires, fire and water are the protagonists of the night. Men and women, young people and children, all dedicate their days and afternoons to the preparation of bonfires. According to tradition, if people jump three times over a bonfire on San Juan's night, they will be cleansed and purified, and their problems burned away.
