Let weather choose the route shape
The day works better when cold winters, hot summers, mountain-edge changes, and pleasant spring or autumn walking are planned into it early.
- Anchor the day around Alexander Nevsky Cathedral or Serdika Roman ruins.
- Keep Boyana Church for the right weather and timing.
Weather in Sofia is not just a packing note. It decides whether Alexander Nevsky Cathedral belongs early, whether Boyana Church still feels sensible, and where you should keep a cafe, mall, museum, or short walk as a fallback.
The practical rule is simple: Alexander Nevsky and Serdika first, Vitosha Boulevard for the soft landing, Boyana or Vitosha as a separate block. That keeps the day grounded instead of making it feel like a loose checklist.
