I play sports (soccer, pickleball, disc golf) all at Schenley and Frick near where I live. Going on hikes/camping. Skiing in the winter. I also have a few friends who get together for chess at new coffee clubs. For solo activities, museums and libraries are nice way to spend a day.

Check out green tree Sportsplex for all year sports leagues. You can sign up as a free agent for any league. M-F 9-12 they have pickleball. Other leagues around the city, but this is a reliable one.

I believe CLP main has a chess club. I see people playing there often, if you want to join my small casual group DM
