Kotor-Mrčevac Road is a very scenic coastal drive located along the Bay of Kotor of the Adriatic Sea, in southwestern Montenegro. It's one of the best coastal drives in the world.
The road is asphalted, and is a loop route. Driving this road is not for the faint at heart. The road often narrow to a single lane, so be careful when passing other cars - you may need to tuck into a driveway or back up to let someone pass. The road is very narrow (one lane in many places) and drops right off the edge into the water in many places (with no guard rails).
The road is really winding and will not fit two cars. It follows (really close) the shoreline of the Boka Kotorska (Bay of Kotor) and is quite nervewracking. You will have to stop and back up to let cars pass and other times had to pull into driveways to let cars pass by.
The road is 19.5km long and links Mrčevac, a small coastal town and Kotor, a city steeped in tradition and history, with remarkable scenic views built between the 12th and 14th centuries.
