There is a local rail service that runs from Bar to Bijelo Polje, passing via Podgorica, Kolasin, and Mojkovac. It is the cheapest method to go from north to south and vice versa, however the service is not of great quality. In recent months, Montenegro acquired new trains from Switzerland, which replaced some of the older rolling equipment used for local services. The standard of quality should be comparable to that of Europe.
Montenegro Railways has also revived the railway line to Niksic, offering a picturesque and reasonably priced trip that is faster than the bus.
This might be the most convenient method to travel about Montenegro. Buses are numerous (particularly during the summer), safe, and often on time. Ticket costs in Montenegro are all less than €15. Prices are as follows: Podgorica-Ulcinj €6, Podgorica-Cetinje €3, Cetinje-Kotor €5, and so on. Local buses do not typically have air conditioning.
Aside from buses, minibuses are available at bus terminals for a little lower price but are a quicker and more comfortable alternative.
Because Montenegro lacks a true motorway, most roads are two-lane only, with the occasional addition of a third overtaking lane, and are usually not up to European standards. Because most roads are winding and hilly, speeds over 80 km/h (50 mph) are seldom permitted and rarely safe.
On the open road, the speed restriction is 80 km/h unless otherwise posted. Within cities, the speed limit is 50km/h.
During the day, the usage of seat belts and headlights is required, and the use of telephones while driving is banned. Signposts in Montenegro are almost similar to those in other EU nations.
Local drivers have a tendency to drive quickly and engage in risky overtaking maneuvers. During the height of the summer season, traffic bottlenecks are frequent. In every Montenegrin city, pedestrians are notorious for jaywalking.
Drivers are notoriously loud, so don’t take it personally if one shouts at you.
There are many vehicle rental companies, with rates starting at 20 EUR per day for a Toyota Yaris.
In Montenegro, hitchhiking is a viable option.
The roads from Podgorica to Bar and Niksic are quite decent and simple to navigate.
The highways from Podgorica to Budva and Petrovac are in in excellent shape, although they are twisty mountain roads that seldom allow speeds over 70km/h.
During the winter, the route from Podgorica north to Kolasin, and then on to Zabljak or Serbia, is considered hazardous, particularly the section through the Moraca canyon. During cold or wet days, it is suggested that one take the bus to the north, since bus drivers are experienced and know the route.
The ancient route from Cetinje to Kotor is mainly a tiny one-lane road with spectacular views of Kotor from above, but use great care while passing on-coming vehicles, overtaking, and going around bends.
