A teenager was airlifted from a Snowdonia mountain after suffering a head injury in a fall.

The 14-year-old was with a school party from Birmingham when he tripped and fell while coming down from an ascent of Tryfan.

Ogwen Valley Mountain Rescue Organisation was called out to deal with the incident about 4pm on Tuesday.

Chris Lloyd of the rescue team said: “The well organised and equipped party had been up Tryfan and were descending the steep footpath from Cwm Bochlwyd into the Ogwen Valley when the boy tripped, taking a 4m [13ft] tumbling fall.”

Mr Lloyd said the boy landed head first against a sharp rock and gashed his head badly.

“He was also complaining of tenderness in several parts of his body,” he added. “Two team members were immediately dispatched to carry out casualty care, whilst other team members gathered at Oggie Base.”

Rescuers also requested the help of a Sea King search and rescue helicopter from RAF Valley on Anglesey.

Mr Lloyd said: “The two team members arrived on scene to find that the remainder of the party had continued their walk off the mountain under supervision while two adults stayed with the casualty.

“They had already dressed the head wound. The boy was then checked for other injuries before the arrival of the helicopter.

“Once the boy was winched aboard, it was decided to fly him directly to Alder Hey Hospital in Liverpool as a precaution against any complications with his injuries.”

Seven Ogwen Valley team members were involved in the rescue.
