TWO of Cornwall's most iconic beaches have temporarily stopped being promoted by the county's tourist board after an "unprecedented" upturn in holidaymakers this summer.

Kynance Cove on the Lizard Peninsula and Porthcurno, near Land's End, have seen such an influx as a result of widespread social media coverage, resulting in Visit Cornwall withdrawing its promotion on their website.

The board claims coastal areas have become overcrowded and traffic is so gridlocked in some areas it has caused safety concerns.

Malcolm Bell, of Visit Cornwall, told the BBC: "Nobody wants to see this sort of mass tourism affecting the area, affecting the tourist experience and clogging the roads."

He called for "redistribution" with more tourists visiting other lesser-known Cornish communities.

"Airbnb has gone ballistic so we've had about an extra 20,000 visitors from that every day - and when the weather is like this often relatives will come down and stay," he said.

A spokesperson from South Western Ambulance Service NHS Foundation Trust said: "This summer we have struggled to reach patients on various occasions due to vehicles being parked inappropriately. We urge people to park sensibly and to show consideration for emergency vehicle access.”

Drivers were pictured getting out of their cars as they waited in huge tailbacks at Porthcurno, while ambulance crews reported being unable to reach patients due to inappropriate parking.

Deborah Hopkins, Unite union regional officer for Cornwall, said the increasing traffic created a "nightmare" for some health workers and trades people.

"Each summer it gets a bit worse," she said. "We need to have a serious discussion about how we balance the need for tourism and the need for business to continue to run over the summer.

"We have a huge proportion of self-employed people in Cornwall who aren't able to make enough money in the summer as travel time isn't paid time if you're in self-employment.

"Our infrastructure is struggling to cope. The burden needs to be recognised and the government needs to invest in Cornwall.”

It is estimated visitor numbers to the county are up by about 20 per cent this year on the usual 4.5 million figure.
