Keep movement honest
The best transport plan is Alexander Nevsky and Serdika first, Vitosha Boulevard for the soft landing, Boyana or Vitosha as a separate block.
- Anchor the day around Alexander Nevsky Cathedral or Serdika Roman ruins.
- Keep Boyana Church for the right weather and timing.
Getting around Sofia becomes easier when you stop treating every stop as equally close. I would choose the base first, group the nearest anchors, and leave the wider move for a clean second block.
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.
