It is difficult to reach Moneglia by car. Unless you want to make a 40 kms detour on a small winding road up and down the surrounding mountains, the only connection is via a narrow tunnel that runs parallel to the coast. This 5 kms long tunnel was used by the train (now the railway has been moved 1 km in the interiors) and it is thus just a bit more than 2 mt wide and completely dark. Driving is only permitted with cars (no bycicles, no trucks) in alternate ways. There is a traffic light (19 min. red light, 1 min. green light) to allow the traffic flow in one direction or the other. You can better reach Moneglia by train.
