The national airline is Montenegro Airlines. Flights to Montenegro depart from various European capitals (Belgrade, Moscow, Paris, Rome and Vienna) year-round for Podgorica Airport and Tivat Airport. In summer there are additional flights, including a direct service from London Gatwick to Tivat. Alternatively, you can fly from London to Vienna with Austrian Airlines and catch a connecting flight to Podgorica. Prices vary dramatically depending on demand and availability.All main towns are connected by decent roads, but caution should be taken on poor roads in rural areas. There are no motorways in Montenegro, but main roads connecting the larger towns, such as the Bar-Podgorica route, are well maintained. The 4 kilometre Sozina Tunnel means that it’s possible to drive from Podgorica to Bar in just 30 minutes. The so-called Adriatic highway, running the length of the coast from Igalo (on the border with Croatia) to Ulcinj (on the border with Albania) is a beautiful but rather tiring drive, and it does get busy in summer.Both international and domestic car hire firms are represented in airports and main towns. Most car hire companies stipulate a minimum age of 21, though some companies say 18. Main cities have metered taxis, which are reasonably priced, though foreigners are sometimes charged higher rates. It is possible to negotiate a fare when the meters are not in use. Only use officially marked taxis. All main towns, as well as many villages, are connected by an extensive network of long-distance buses, which are reasonably priced but do get crowded, especially along the coast in summer. Major routes include Kotor-Budva-Bar and Bar-Podgorica.The national rail network is being upgraded. Due to the country’s mountainous terrain, railways are difficult to build and require tunnels and bridges. Some routes are exceptionally scenic, most notably the stretch from Kolašin to Podgorica. Bar, Podgorica, Kolašin, Mojkovac and Bijelo Polje are on the main railway line running to Serbia. A local line runs from Podgorica to Nikšić, passing through Danilovgrad en route. Timetables are available from Railway Transport of Montenegro.
