Helsinki offers plenty of cultural programme during Helsinki Festival the last couple of weeks of August (please see Helsingin juhlaviikot for the programme and to buy tickets). There is loads of free programme and activities offered to all ages on the Kansalaistori square next to the Music Centre. We happened to pass the square pretty early today, and had to stop to blow giant soap bubbles and add to the jungle of a colourful web of strings. We might be back e.g. for a story time or circus tricks. I would also consider the outdoor movie picnics on the three last evenings in August at 9 pm, if a babysitter turns up automatically (the movies are hardly for children). Please find all the programme in the square here.
