Llanberis Mountain Rescue
Volunteer heroes saving lives on Snowdon and the mountains of North Wales
About LMRT
On the eleventh of November, 2023, our son William Dennis Onion fell from Crib Goch.
The air ambulance arrived first, but it was Llanberis Mountain Rescue who made it to him. It was Llanberis who went up that mountain when others could not. It was Llanberis who brought William home to us.
They did not just save lives that day. They carried the weight of the ones they could not save. They looked after William’s friends when the unimaginable had happened. They comforted the traumatised, the injured, the grieving. They did what few could do. And they did it without hesitation.


Why We Support Them
Six people were on that ridge with William. Dan and Mollie risked their own lives trying to get to him. They were airlifted down alongside his body, and spent over four hours in the Llanberis team’s kitchen, waiting for the rest of the group to come down. That is how limited the facilities are. A church hall. A kitchen. No private space to grieve. No proper rooms for the traumatised or injured. But the care they received was extraordinary.
The rest of the group Kelly, Rebecca, and Sarah were still up on the ridge. They had seen William fall. They were in shock. Cold. Frozen in body and mind. A helicopter tried to reach them but could not land. So the Llanberis team climbed up. They winched them. Guided them. Roped them down step by step. All of this in the dark, on a knife-edge ridge, with the weather closing in. For four hours, they brought them back to safety.
All volunteers. All unpaid. All giving everything they had.
