If you like long long walks, you could check out trail running / ultramarathon groups. Lots of people to meet at free running nights, which is twice a week at every running store. You don't even have to run! Just walk!

Do you have a dog? You could do dog training. Do you do art? You could take art classes. Do you like to code? (Obviously) Go to coding meetups. Do you like writing/poetry? Go to poetry / open mic night. Do you like games? Check out gaming stores for social events.

Do NOT expect to get dates at these places: that's a bad strategy. But try to meet friends at these places. You meet partners by proxy, and by having fun with your friends.

As a straight male: it's a lot easier to meet guys than to meet girls. Use that strategy.
