I've moved countries a lot, doing contracts. One of the finest resources that I've found is meetup.com
You sign up, give your city, and your interests, and it starts suggesting social groups and events for you! I've used it to meet people and try new things when I lived in Vancouver, and now here in Melbourne, Australia.
We can't tell you what to do or where to go - that's subjective and polling, and far too open ended. But hopefully this will show you HOW to find these things.
