A WARNING for the public to stay out of a 'dangerous' quarry and bomb storage site has been issued.

Every year swimmers, climbers and fun seekers break into Glyn Rhonwy on the outskirts of Llanberis.

The water-filled quarry hole, which is close to a former World War Two abandoned ammunition facility, attracts people as the weather warms up.

Now, Gwynedd Council is issuing its annual warning for people to stay away and to respect signs warning of potential dangers.

According to the council, in the past, there have been a number reports of people either breaking or scaling the six foot steel perimeter fence at the former industrial site.

Gwynedd Council’s economy Cabinet Member, Councillor Gareth Thomas said:

“The former industrial site at Glyn Rhonwy is closed off for a reason.

"Anyone who ignores the numerous signs placed on the perimeter fencing is putting themselves into unnecessary danger.

“The quarry pools that have been used for swimming by trespassers contain a number of potential hazards which could cause serious injury or worse.

"Hazards include under-water debris and jagged slate shards.

"It should also be remembered that the water temperature in these pools is usually dangerously cold even during prolonged periods of warm weather.

“We have in the past reported this matter to North Wales Police.

"We would urge anyone who witnesses people trespassing on the site to contact them immediately by phoning 101 or phoning 999 if someone is in danger.

“Our message to the public is simple - please keep out of this dangerous site.

"We are also appealing to parents to ensure that their children are aware of the dangers of trespassing on old industrial sites.

"Avoid swimming in any pools or lakes which may contain hidden dangers such as underwater currents or sudden deep water.”
