The view from the summit over the top of the old cafe building

Last week Gwyn Roberts of Llanberis Mountain Rescue said people were getting into trouble because they were overstretching themselves.

This weekend another four people were airlifted from the mountainside.

Three of those airlifted were with the same walking group of nine teenagers and adults.

A Sea King helicopter based at RAF Valley airlifted the first casualty off the mountain just below the summit of Lliwedd.

Because the helicopter was low on fuel, Llanberis Mountain Rescue was sent to escort the rest of the group off the mountain.

Rescuers then found a second woman had a suspected broken wrist and back injuries.

A "good Samaritan" who had stopped to help also suffered a suspected dislocated knee.

The two casualties, along with the leader of the original group, then had to be airlifted from the mountain.

Two other members of the original group continued alone across Snowdon - they were picked up later safe and well at Llanberis.

Dr Gwyn Roberts, chairman of the rescue team, said their advice was that groups should always have properly experienced leaders.

Meanwhile, the cafe at the summit of Snowdon closed for the last time over the weekend in preparation for its demolition to make way for a new building.

The Snowdon Mountain Railway has also stopped running its trains all the way the top whilst the work on the new building goes on.
