My first thought is going for walks around where you live. If there are green spaces along the way that’s even better. You can turn it into kind of a workout where you do longer and longer walks, or the same length but a little faster each time.

It’s a good way to clear your mind, it also never hurts to be active.

I like going for a walk around the city or to the Rhine river and watch the ships go by.

If you’re the social kind, go to the park and ask someone who plays frisbee or other activity to join in.

Running is a great sport that’s relatively cheap and also helps against depression.

Geocaching is fun alone and with other people, but not in the city (in my opinion).

Check your local newspaper and see what events are going on. Sometimes events are cheap or even free.

chess or other board games are inexpensive and you can learn a lot and make friends along the way.

Fotography can be expensive, but if you do it just as a hobby, you could take your phone or get a cheap camera and try to get up early on weekends and take some photos of the city.

reading books, especially about animals (specifically birds) could be an option too.

The city where I live has a musical instrument lending library. I don’t know how common these are? Ours started when a cherished local musician passed away and his eclectic collection became the library. Over the years, more people have donated instruments and there is an annual festival to raise funds for their upkeep. (As a local musician, I’m actually playing at said festival today.)

Anyway, it works just like a regular library. You get your library card and check out an instrument and it doesn’t cost you a penny. And there are all kinds of videos online these days to give you pointers on how to play. I guess if you get really serious, you’ll probably want some one-on-one tutoring, but if you’re just doing it for kicks and don’t have any plans to join a band or whatever, you can just have some fun and see how far you can get on your own?

Groups and clubs. They exist, you need to find them. The public library is a good place to start looking.

Frisbee golf, biking, rollerblading, skateboarding, gardening, cooking, painting, geocaching, hiking, fishing are all pretty cheap to get into.

Have you got a seat filler company? It’s a company that you pay a small amount to go to gigs, theatre, events, etc that have been undersold. They just want people to fill the seats. I pay around £3 a time and I’ve seen bands like Kiss, Less Than Jake, Fun Lovin Criminals, not free but cheaper than a coffee.

Geocaching is free and usually lots of fun in cities. It’s like a big database of dead drops - people hide small containers with pieces of paper to sign, and post their GPS coordinates online. Frequently they’re hidden near points if interest, as well so you might find some cool shops or bars as a side effect.

Photography is free if you have a smartphone.

Find a game store! Every city should have one or two places where people gather to play board games and card games. I’ve met some really great people just jumping into random magic the gathering matches. Only of my best friends was just some dude I met at the card shop, he was looking for a group to play dnd with and we’ve been meeting up once a week ever since.

Apps like meet up (if it’s still a thing?) may be really useful as well.

skateboarding

a decent starter one will run you $100 at the most, pads can be found for cheap; all you need is a flat surface and a non-rainy day. you will fall a lot but enter into a worldwide community that has its own very real culture. keeps you fit, gets you outside, lets you meet people. best investment in my life

Maybe getting a gym membership, if it’s cheap and you’re interested?
I’ve not gotten one, but have heard of friends n others who found decent friends in the gym.

And the exercise may help with the general mood too.

Community theater is great for meeting people and usually basically free

If you have a university in your town often they will have some clubs that are open to the whole community and occasionally public lectures.

Museums and art galleries are usually pretty cheap especially if you keep your eyes open for the free stuff. I go whenever I see free stuff, or a new exhibit I’m particularly interested in.

I know people that do the indie concert scene, just going for any random concert under 20 bucks. Sometimes the bad ones can be just as entertaining as the good. you go to maybe 1 show a week and spend the rest finding the concerts and maybe listening to them on spotify/sound cloud.

Indie movie theaters can also be a vibe. Mine is about 10bucks a ticket, but sometimes they have a free night and sometimes a pay what you can deal. I go every month or so. Last one was a scooby doo one, it had a “cheer whenever they say scooby” game, a drinking game and the previews were funny clips about scooby (robot chicken and that sort of thing) it is a very social experience and a lot of fun. Not free but clearly not for profit.

I think the best thing is to just walk around more, and just be on the eye out for stuff that interests you. Actually read the fliers on posts, join local social media groups to find out what’s up, keep an open mind and look to push your comfort zone and look out for local community stuff over corporate for profit stuff.

Pokemon Go. It will entice you to take long walks in areas that you may otherwise not visit. I moved from a rural area to a big city and play Pokémon Go daily with my pup, rain or shine. We end up spending hours outdoors and it’s done great things for my mental health.

• The city where I live in has several few Little libraries that people have in their garden or hanging at the wall of their home. And I know that other cities have them as well. Today I went biking and brought back two books and I was pretty sure that I did not want to take any because I have more than enough to read, but I noticed an interesting book and took it home. This is something you can do yourself. Build a small wooden box, and have other people put or take books. You don’t have to do this yourself, you could ask friends, family and co-workers to help you build it or ask them to provide such. Then you could take a little bit care of it and promote the idea.

• What I like about bigger cities are public parks. I like to go to parks and just sit, listen to birds, enjoy the green and in Springtime, Summer and Autumn enjoy the colors.

• Public libraries here have magazines and books to read for any visitors. I’ve learned about open source software thanks to the Internet but also a little bit thanks to public libraries. I find that reading paper books or magazine can also be a nice break from staring at a screen of a device.
