The teenager was assisted by the Woodhead Mountain Rescue Team after the Yorkshire Ambulance Service were called out.
The youngster had fallen from a rope swing on the trail between Cudworth and Lundwood, and was treated for a suspected broken arm.
A spokesperson for the team said: “After a short drive along the trail in the vehicle, team members were able to assess the casualty and provide the appropriate care.
“Fortunately, a passer by trained in first aid was able to supply a make-shift sling for a suspected broken arm.
“The young boy was further treated for his injuries but otherwise in good spirits.
“In the end, the young boy was able to walk off to the waiting ambulance for his onward journey to the hospital.”
