An 18-year-old girl has been killed after plunging 30ft over a waterfall at a beauty spot in a national park.

Carley Andrews, from Flint, was walking with friends in the Snowdonia National Park, north Wales, when she fell from the edge of the waterfall at Pontgyfyng near Capel Curig, Gwynedd, on Sunday.

It is thought the group had been canyoning without proper equipment.

Emergency services were called, with the mountain rescue teams and a helicopter from RAF Valley.

'Impromptu canyoning'

Her body was recovered from the rocks by rescuers.

Chris Lloyd, spokesman for Ogwen Valley Mountain Rescue Service, said: "It seems she had fallen down a small waterfall and either been trapped by the current and drowned or had banged her head.

"I couldn't see any visible injury but although she was given mouth-to-mouth resuscitation, she didn't regain consciousness.

"It looks as if the woman and her friends had decided to do some impromptu canyoning but without any equipment.

"It can be a dangerous sport and you should have helmets and buoyancy aids because the rocks are very slippery and the river can be unpredictable."
