The Rail Network at a Glance
BDZ operates Bulgaria's rail network, a no-frills system that connects Sofia, Plovdiv, Varna, and Burgas on lines that cut through the Balkans. Service is basic but functional, and prices are among Europe's cheapest. The mountain routes have a rougher charm if you have time to spare.
How Eurail Works in Bulgaria
Eurail passes cover BDZ trains. We recommend the pass only if you're combining Bulgaria with Romania or Greece. For point-to-point travel within Bulgaria, tickets are so inexpensive that advance booking makes more sense than a pass.
Popular City-Pair Routes
Sofia to Plovdiv. ~2.5 hours on express trains running 8 times daily. No reservation required. Approximately €5-8 (~$5-9 USD). Plovdiv is Bulgaria's second city, older than Athens, perched on hills overlooking a river valley.
Sofia to Varna. ~7-8 hours on IR trains. Varna is the Black Sea's main resort city, with beaches and a lively seaside atmosphere. It's a full-day journey but prices are minimal.
Sofia to Burgas. ~7 hours on regional trains. Burgas is a working port city with a less touristy vibe than Varna, and it's the jumping-off point for beach villages south along the coast.
Plovdiv to Burgas. ~5 hours. The inland route drops down toward the sea through the Rhodope foothills.
Sofia to Veliko Tarnovo. ~5 hours on slow trains. Veliko Tarnovo is the medieval capital, dramatically sited on a river gorge with Ottoman and Byzantine ruins clinging to the cliffs.
Scenic Routes & Day Trips by Rail
The Rhodope Mountain narrow-gauge line from Septemvri to Bansko is one of the Balkans' most scenic train routes, switchbacking up the mountain with valleys opening below. The Iskar Gorge route from Sofia to Mezdra climbs through dramatic red-rock formations and is worth riding just for the views, even if you don't stay in Mezdra. Both routes are slow but unforgettable.
Practical Tips for Bulgaria
Buy tickets at station windows. BDZ's website is minimal. Staff speak little English, so have your destination written down. Trains vary in comfort from modern to basic. Bring snacks. The slower the train, the more picturesque the journey. Expect delays on regional lines. Conductors are friendly but stern about seat assignments.
Cross-Border Connections
Sofia connects to Thessaloniki, Greece (~7 hours), Belgrade, Serbia (~8 hours), Bucharest, Romania (~10 hours), and Istanbul, Turkey (~12 hours). See our guides to Greece, Serbia, Romania, and Turkey for onward travel.
