Air travel is comparatively cheap, and is only slightly more expensive than rail travel. Regular boat and hydrofoil services along the Bulgarian bank of the Danube link many centres, including Vidin, Lom, Kozloduj, Orjahovo, Nikopol, Svishtov, Tutrakan and Silistra. Bulgarian State Railways connects Sofia with main towns. Reservations are essential and first-class travel is advised. For details contact the State Railway Office.
Traffic drives on the right.
International road signs are used, although roadworks are often not signposted. Night driving can be dangerous owing to poor lighting. Foreign drivers are sometimes liable to extra road tolls. In addition, the driver may be banned from driving in Bulgaria for up to 3 years. Spare parts are easily available.
