Stopover in Sofia : what to do and when to leave
SOF is divided between T1 and T2; The M4 metro starts next to T2 and connects with the center. A departure only compensates with real margin for the shuttle between terminals and the return to security.
With less than 8 hours, stay in SOF. From 9–11 hours the center can fit if you can enter Bulgaria, the baggage is checked through to the final destination and you reserve two and a half hours to return.
Your safety comes first. Reviewed on August 18, 2026 · Guidance, not immigration authorization.
