A climber has captured on film the terrifying moment he slipped and fell down one of the highest mountains in the UK.

Mark Roberts, 47, was attempting to scale Snowdon in north Wales with two companions.

On reaching the Parsley Fern Lefthand Gully, Roberts - a lifelong climber - was hit by a chunk of falling ice and fell.

He tumbled 100ft down the mountainside before he was stopped by a ledge. Throughout the fall, his head-mounted camera was running.

Roberts, a safety consultant, was rescued by the Llanberis Mountain Rescue team and taken to a hospital in Bangor. He escaped without serious injury.

Roberts told the British Mountaineering Council's (BMC) website: "When it all happens so quickly, you just try not panic and hope there's some luck with you.

"There was no feeling of panic, more a concerted effort to protect my head and neck and be aware of what was below me, where I was heading and what I could do to slow and stop myself before I got to the more serious rocky outcrops.

"I was a little dazed but, critically, not unconscious. I had the foresight to check the cam was still attached and just hoped the vid had recorded. It wasn't one for repeating"

Elfyn Jones, BMC conservation officer for Wales and member of the Llanberis Mountain Rescue Team, said: "The key message here is that accidents do happen, but that Mark was well equipped and wearing a helmet and that probably saved his life.

"The other climbers in the area did exactly the right thing. His friend dialled 999 and asked for the police as soon as they saw the fall, and he was lucky in that two members of the mountain rescue were climbing nearby."
