In short: Bus is faster (7–8 hours, €15–25) and more frequent. Train takes 8–10 hours and is more comfortable but slower. For most travellers, the bus is the practical choice. Via Niš either way — consider a night stop there.
Bus: FlixBus, Eurolines, local operators. Daily direct services. €15–25. 7–8 hours. Book via FlixBus.com or Omio.
Train: 1–2 daily services via Srbija Voz/BDZ. 8–10 hours. From ~€20 second class. More comfortable seat; limited schedule flexibility.
Verdict: Bus wins on frequency and booking ease. Train wins on comfort. The time gap (2 hours) is significant on a long journey. If you have a Eurail pass, the train makes more economic sense.
Niš detour: Both bus and train pass through Niš. The Skull Tower (Ćele Kula) and Niš Fortress are genuinely remarkable. A one-night stop is one of the most underrated moves on the Western Balkans circuit.
Border note: Bulgaria is now fully Schengen (since early 2025). Entry to Bulgaria counts as a Schengen entry — EES biometrics apply for non-EU nationals at the border.
