Four men were rescued from the highest hill in the Brecon Beacons after getting lost in bad weather.
Three of the walkers were shod in sandals and one was suffering from a heart problem.
Four rescue teams yesterday went to the aid of the men who were found on the Cefn Cwm Llwch ridge, north of the summit of Pen y Fan.
Central Beacons Mountain Rescue Team were alerted at 7.45pm on Sunday after reports of an unwell walker on the 886m (2,907ft) mountain. The team was joined by colleagues form the Brecon Mountain Rescue Team, Western Beacons Mountain Search and Rescue Team and the Longtown Mountain Rescue Team.
After setting off from the Storey Arms, the rescuers found the men in high winds and conditions described as very poor.
Three of the men were helped from the hill, and the fourth was stretchered to a waiting ambulance.
A spokesperson for the Central Beacons MRT said: “The men who had been camping in the national park for the weekend had become disorientated in the poor weather and their problems were then compounded by the heart condition of the casualty.
“All four reached safe ground with assistance of the teams and the casualty was transported to Neville Hall Hospital in Abergavenny.”
Spokesmen from the teams questioned the equipment and preparedness of three of the men who were rescued, and advised that mountain boots may be a better option than sandals in poor weather.
