Sant Joan Main Festival of Valls Activity · Valls, Alt Camp, Tarragona The Festa Major de Sant Joan Baptista de Valls opens the calendar of summer patronal festivals in Camp de Tarragona and coincides with the summer solstice. It preserves elements of deep-rooted tradition, such as the Completes and the sound of the sonadors, and it is also the festival that opens the human-tower (castellera) season in Catalonia, with the rivalry between the colles Vella and Joves Xiquets de Valls in an urban setting considered the kilometre zero of the castellera world. It is celebrated with bonfires on the Nit de Sant Joan and with boladís, a drink of anise and cold water descended from bolado, an artisanal sweet documented since 1745 that the French writer Alexandre Dumas praised in 1846, during his journey across the peninsula, for its ability to make water sweet, cool and fragrant. 24 de juny Photo: Jordiferrer (CC BY-SA 3.0) What to see and do in Valls
