I am 30(ish) and have managed to avoid the online dating scene. I just met people doing the hobbies I like and traveling. I feel like now it's easier than ever to do that. COVID has made a lot more people travel (anecdotal data ofc) after they felt stuck for a while. And remote work means that you can travel while working.
You can go somewhere, meet someone, and then travel around together. If things stop going well, just stop traveling together. Stay at hostels, work at co-working spaces, look for 'expat groups' on Facebook (had to reactivate my Facebook account for this one). Get some hobbies and move to places that you can do them (live in a ski resort for a season or a surfer town and go snowboarding/surfing everyday). The person you meet will most likely be doing the same thing you're doing, so at least you have something in common (hobbies/traveling).
The best part is, even if you don't meet someone, you probably had fun doing stuff rather than sitting at home and swiping on tinder. The only downside is the environmental impact of traveling around :(.
