What hobbies/ classes to try solo as someone in my mid-20s? Any good pickleball courts?

Hi everyone, I’m in Chennai for a few months visiting some relatives. I’ve been meaning to try to out some hobbies as a solo person, because I don’t have friends or cousins of my age in this city. I heard pickle ball is quite popular now. If anyone has played, please recommend good courts near Adyar, Ecr or Omr with many number of players. Or if there are any other activities too, please mention them below!
