Visitors to Wales’ highest mountain are being urged to respect others by not skipping queues to reach the top following rows among climbers.

Recent hot weather means there have been bumper summer crowds at Yr Wyddfa, also known as Snowdon, where people have reportedly waited more than one hour to reach the 1,085m (3,560ft)-high summit.

Social media videos have shown arguments among queue-jumpers and those patiently waiting their turn to touch the metal plate that marks the top.

A recent video showed Marc Screeton, from Manchester, being heckled as he bypassed the line, saying: “Imagine queuing on a mountain? No chance.”

But others have said queuing is necessary for safety reasons.

Eryri National Park Authority said its policy remained one of “self-policing” at the summit.

The mountain’s growing popularity in Eryri National Park, also known as Snowdonia, has led to bottlenecks, and queues are now common on the stone steps leading to a metal plate or trig point where people pose for photos and videos.

Two charity hikers raising money for motor neurone disease were booed after skipping queues to reach the summit in May.

Speaking to BBC Wales, walkers on the mountain had mixed views about those jumping the queues.

Lucy Taylor said: “I think you should queue because it’s really quite dangerous and everyone’s trying to get up there – it’s just not safe.”

Tina Millard from West Bromwich said: “I don’t think that you should have to queue.

“It’s a mountain, you should just be able to go up and that’s it.

“We’re not at Alton Towers for a ride. It’s a mountain, it’s for everyone,” she said.

Carl Lynch from Dunstable, Bedfordshire said: “It should be: ‘go up there, two minutes and then move on for everyone else’. Simple as that.”

Throughout this year’s hot weather national park wardens have urged visitors to follow the country code by leaving gates as they found them, taking their litter away with them and reducing the risks of wildfires.

They have also urged people to wait their turn when queuing.

Alun Jones, an area warden for Eryri National Park Authority, urged those wanting to reach the trig point to be “considerate and don’t skip the queue”.

While queuing is often not compulsory, it is often an “unwritten and unspoken” social contract, according to an expert in moral philosophy.

Johann Go, who is also assistant professor of ethics at University College London, said: “So it’s not that I have to queue, but given that others are already restraining themselves, if I were to then jump the queue, I would be saying ‘to hell with them’ and that my time is more valuable.”

In May a pair of charity hikers were met with jeers from a queue at the summit as they tapped the trig point to complete a charity challenge.

Jamie Richardson, 32, and Richard Thiedeman, 34, from Lincolnshire, were climbing Yr Wyddfa as part of the Three Peaks challenge to raise money for their friend who has motor neurone disease (MND).

“I was getting booed and then there was a gentleman who was at the top, who had just had his photo taken and he physically tried to stop me,” Richardson said.

He said he had just touched the summit point and heard someone say “you should be ashamed of yourself”.

Richardson added: “There’s no policing of it at all, it is purely free will, if you want to queue you can.

“The queuing, that is just purely down to British culture traditions.”

On social media, some described the scenes at the mountain over the May bank holiday weekend as having a carnival atmosphere due to the crowds there.

A spokesman for the Eryri National Park Authority said it had “no plans to intervene in a dispute over hikers queuing at the top of Yr Wyddfa”.

He said: “There are three quarters of a million people summitting annually, so queues are likely to be expected in peak times.”

He added there were no plans for new measures to be implemented this year, but the matter would be discussed at an end of visitor season meeting in the early autumn.
