Swimmers have been spotted taking a dip in a toxic pool – despite warnings to stay away.
People were seen diving into the electric blue water in a former quarry known locally as the Blue Lagoon, just other the county border in Buxton, on Bank Holiday Monday (May 25).
Families have even been travelling from Staffordshire and Yorkshire to the site in Harpur Hill on the edge of the Peak District.
However, anyone planning to the Blue Lagoon is being warned is like having a ‘bath in bleach’ due to the PH level.
There are also old cars, animal carcasses and faeces in the water.
And Derbyshire’s Chief Constable has described the pool as “probably the most dangerous water in the UK”.
Now people are being reminded to stay away over half-term.
Danielle, aged 22, from Sheffield, told DerbyshireLive: “My family has been coming here for years so I thought it would be busy but I didn’t expect it to be this busy to be fair.
“We’ve just come down with the kids for a picnic but I don’t think we’ll stop for long. I can’t believe how busy it is.
“I’m amazed people are swimming. The signs make it obvious how dangerous it is.”

Earlier this year, Derbyshire Police faced criticism for for pouring black dye into the water to deter visitors.
Lord Sumption even called it “disgraceful”, saying: “This is what a police state is like, it is a state in which a government can issue orders or express preferences with no legal authority and the police will enforce ministers’ wishes.”
The lake is, in fact, dyed black every year in an effort to make the site look less appealing to visitors, as the water is otherwise a lovely crystal blue colour.
A Derbyshire Fire and Rescue Service spokesman said: “We’re aware of people continuing to visit Harpur Hill quarry, known locally as the Blue Lagoon.
“Did you know it gets its blue colour from toxic deposits seeping from the quarry stone and is the same PH value as bleach!
“Would you swim there? #StayAway.”
Derbyshire’s Chief Constable Peter Goodman previously said: “That area was a quarry near Buxton and the water in there looks like a very attractive blue because it is full of chemicals.
“It looks attractive, so lots of people go there.

“But it is probably the most dangerous water in the UK, experts say.
“It is highly alkaline and is full of chemicals. It is like going for a bath in bleach.
“Every year we have been trying to make it look less attractive so people won’t go there. It is not that coronavirus that has done this, we do it every year.”
