Authorities crack down on trade they says risks spiralling out of control – but operators say they are being targeted unfairly

On the edge of Piazza Navona, one of the grandest squares in central Rome, Barry and Linda, visitors from Texas in the US, stepped out of a golf cart. They planned to cross the square on foot, perhaps stopping to admire Lorenzo Bernini’s 17th-century Fountain of the Four Rivers, before being picked up by their driver at the opposite end.

The couple had already done a walking tour on day one of their trip, and had been so exasperated by a stifling three-hour shuffle along a corridor towards the Sistine Chapel on day two that by the third day they wanted to give their tired feet a rest.

Tourists blocking streets and indulging in ‘dangerous’ behaviour, say Sicilian officials

Thousands of tourists have flocked to Mount Etna to watch spectacular eruptions on the volcano, but some people are blocking streets and preventing rescue services from reaching those in need of assistance, the local authorities have said.

Sicily’s head of regional civil protection, Salvo Cocina, described the tourism of recent days at Etna as “wild” and “extremely dangerous”, warning that day-trippers drawn by the exceptional views had parked their cars along narrow streets, impeding rescue vehicles.
