Their pastel-coloured houses and tiny fishing harbours make them one of Italy's most popular destinations, but a string of picturesque fishing villages known as the Cinque Terre fear they are being suffocated by mass tourism.
The opening of a new cruise ship terminal at the nearby port of La Spezia has increased by around 30 per cent the number of day-trippers who swarm through the villages, crowding narrow alleyways and overwhelming local services.
The new terminal has led to a dramatic rise in the number of cruise ship passengers arriving, from 470,000 last year to a projected total this year of 645,000, according to port authority figures.
Every time a liner docks in La Spezia it disgorges thousands of passengers on to coaches destined for the picture-postcard villages of Manarola, Vernazza, Corniglia, Riomaggiore and Monterosso.
The inhabitants of the Cinque Terre, which literally translates as the Five Lands, say the huge numbers of visitors threaten to ruin the very thing they have come to see.
