One of the most important elements of the Semana Grande is, without a doubt, the International Fireworks Contest, which includes the participation of companies from different parts of the world.
Also, music has an important place in the festival. Great musical stars gather in the capital of Gipuzkoa.
As far as sports is concerned, it is worth mentioning the classic swimming crossing from Getaria to San Sebastian, horse races, the beach-volleyball tournament and “herri-kirolak” exhibitions (Basque rural sports).
Furthermore, and like in previous years, children will have at their disposal workshops, games, gigantes and cabezudos parades, disco, toros de fuego (fire bulls), and so on.
