Rescuers against jumping from a Brecon Beacons waterfall after the third callout to the site in the past year.
Western Beacons Mountain Search and Rescue Team was joined by colleagues from the Brecon and Central Beacons teams at the incident at Sgŵd Gwladus on Saturday.
Dyfed-Powys Police alerted rescuers shortly before 4pm after a request from ambulance staff who were dealing with the person who was reported to have suffered potentially serious injuries when they jumped from the fall, north of Pontneddfechan.
Mountain Rescue Team members immobilised the casualty using a vacuum mattress before using a team vehicle to take the injured person to a waiting ambulance.
A Western Beacons team spokesperson said: “This is the third incident of this kind at Sgŵd Gwladus in the last 12 months and we urge anyone considering jumping off the fall to consider carefully the potential for life-changing injury or even death should things go wrong.
“There are numerous professional outdoor pursuits companies with a wealth of local knowledge who provide gorge walking activities in the area.
“Our best wishes to the casualty for a full and speedy recovery.”
