Nature has its way of derailing travel plans. A landslide in August 2023 in the French Alps blocked the main railway just west of the Mont Cenis tunnel. This route is used by all trains from Italy to Lyon and Paris. The sleek French TGVs and the even sleeker Italian Frecciarossa trains competing on the lucrative link from Milan to the French capital were stopped in their tracks.

Many passengers bound for Paris and London from Italy rerouted through Switzerland, while others devised creative itineraries via the Riviera, using the historic railway running west from Genoa which, in 1872, became one of the first two routes crossing the frontier from Italy into France. The Mont Cenis route still hasn’t reopened so, needing to travel from Trieste to France, I opt for a dose of Ligurian sunshine and take the train via Genoa, following the coast west from there into France.
