Things to do in Portland OR in your 20s?

Hey Guys. I just moved to Portland Oregon from Southern California by myself and I don’t know what to do with my spare time. I have a job and am starting to meet people but I would love some ideas to do in the city/surrounding area. I’d love things I can do solo but also places I can meet people since I don’t have any friends here yet. Thanks so much!

Extra information: I’m 21 and I love hiking and I’ve already done several! I like going to bars but I don’t want to go out alone so maybe that can wait until I make a friend. Other ideas?
