A teenager on a Duke of Edinburgh’s Award expedition was rescued after suffering exhaustion on a Snowdonia hill.

The 17-year-old girl was with six others undertaking a gold award route on Wednesday north of Moel Meirch in the Nant Gwynant area.

Aberglaslyn Mountain Rescue Team was called out about 9.25pm and a Sea King helicopter from RAF Valley on Anglesey also flew to the scene.

A team spokesperson said: “The RAF search and rescue helicopter successfully located the group high on the mountainside, and evacuated the group to the roadside and waiting ambulances at Pont Bethania, Nant Gwynant.

“The female was treated for symptoms of dehydration and released into the care of the group leaders.

“However whilst at Pont Bethania, another member of the group began to complain of chest pains, and that the pains had been occurring periodically throughout the day.

“She was assessed by team members and although seemingly fit and well, was advised to attend at the nearest hospital for further checks.”

The rescue ended about 1.10am.
