Fantastic, love that they do this. Really great for locals and visitor... great way to experience Krakow. Park Bednarskiego is just so beautiful to begin with and when there is all this cool stuff and the sun is shining... well, you just wanna hang out there every single weekend! There is always an awesome selection of food from some of the best places in Krakow. I don't have kids or a dog myself but there are lot's of families and the kids seem to have a blast so bring 'em along if you have 'em. Also there are soutdoor film screenings in Park Bednarskiego and other parks in summer but don't know if it's the same organisers
The biggest and the best climbing centre in Krakow. Children love this place too!
