Clubs/Events/activities in summer?

Hi everyone.

This is probably my last extended summer break ever, currently finishing my mémoire and planning to chill for summer. I'm thinking about trying new things, join clubs or whatever. I've been singing in a few choirs already, I like singing. But I want to experiment, thought about joining urban dance, or join a martial art class. Do you have any recommendations? Any suggestion of any kind is welcome.
