The water may look clear and inviting but campaigners in Buxton are desperate to warn people off a popular beauty spot known as the 'Blue Lagoon.' Experts say the water is almost as toxic as bleach.
With the hot weather recently though hundreds are flocking to the site and jumping right in.
The blue colour of the water is caused by the surrounding limestone rocks which turns it into what looks like a little bit of paradise when instead the site comes with a health warning.
Signs close to the shoreline warn the water could cause skin and stomach problems. Other warnings including ones stating the water is known to contain abandoned cars and human waste, but it has a pH level of 11.3 – compared with 12.6 for bleach.
