Spending the Summer in Nuremberg ! Suggestions for making friends and activities??

I’m going to be spending most of my summer in Nuremberg with my family, and I really don’t want to spend it just sitting at home. I don’t know anyone here yet, so I’d love to meet people, make some friends, and try new things.
I’m a teenager and I’m pretty creative, so I’d be interested in art classes, drawing workshops, theatre groups, or anything artsy. I also like being outdoors, so football, skate parks, hiking, or other outdoor activities sound really fun.
I’d also be interested in volunteering or joining heritage projects in or around Nuremberg—maybe helping out at historical sites or doing something meaningful during the summer.
My German is only around A2 level, so I’m mainly looking for activities where I don’t need perfect German.
