Montenegro Airlines flies from Podgorica to Budapest, Frankfurt and Zürich. Austrian Airlines, Alitalia and Lufthansa fly into Podgorica. JAT (Yugoslav Airlines) flies from Belgrade to Podgorica and Tivat several times daily.
Rail services run into Montenegro from Belgrade.
Drivers from Britain, Spain, Germany and some other countries need an international driving licence; otherwise visitors can use their national licences. Vehicles need third-party insurance plus insurance bought at the border. Traffic police are everywhere so drive carefully and stick assiduously to speed limits.
A ferry service operates between Bar and Bari in.
Buses are the best way to get around, as they go just about everywhere. Train services are quite limited in Montenegro, though there's a very scenic trip into the coastal town of Bar. If you want to travel along the Montenegrin coast, or visit Durmitor, you'll have to catch a bus.
VIP, Hertz, Europcar and Net Rent-a-Car all have offices at Belgrade airport and in the major cities.
