Salou has two great events in one evening coming up. On Saturday 22nd August at 8 pm there'll be "Sardanas" the traditional Catalan folk dance close to the Sports Port.
After that, walk just 500 metres to the Plaça Venus (Camping Sanguli area) and hear the "Habaneres" Cuban style folk singing, starting at 10pm.
This is repeated on the following Saturday 29th and the Sardanas only on the day of the Diada de Catlunya (public Hoiday) on the 11th September.
There will also be street shows on the "Paseo" near to the statue/bis station on the 30th August, 13th, 20th and 27th September.
