One of Europe's most scenic train rides leaves from Locarno, following lofty tracks perched high above the Melezza River and its tributaries.
Over millennia, the snow melting from the Alps has caused each of these rivers to carve a deep valley - reputedly 100 of them, hence the name centovalli.
Charming vintage rail cars go slowly enough to allow views down into these steep, wooded ravines as the train crosses 83 bridges on its way to Domodossola, the Italian town at the foot of the Simplon Pass.
