From Nice to Monaco, there’s a choice of two ridiculously scenic bus routes, setting you back just €2.50, or €2.10 if you buy your ticket online at zou.maregionsud.fr.

Fortunately, this part of the coastline along the Côte d’Azur is well connected by rail, and you can whizz your way from Nice to Monaco for a mere £6 ($8), or even less if you book in advance.
