Gradina – Kalotina

The principal Serbia–Bulgaria crossing and a major freight and transit artery toward Sofia, Istanbul and Greece. Trucks form the longest queues here, especially on weekday nights; cars move faster outside the summer holiday peaks. Both terminals run around the clock.

EES / ETIAS

Bulgaria is now in the Schengen Area, so the EU Entry/Exit System applies on the Bulgarian side for non-EU travellers.

Tip

For cars, the quietest window is usually mid-morning on weekdays; freight is steadier overnight.
