The Bolton Mountain Rescue Team was called to Horwich yesterday after a woman suffered a serious leg injury while out walking.
The 32-year-old had been out in Tiger's Clough and had fallen in a steep-sided river valley.
The North West Ambulance Service requested the help of the mountain rescue service at 3pm yesterday and they arrived within 20 minutes.
A spokesperson for the rescue service said: "The female casualty was given strong painkillers before being carried out of the valley to the nearby ambulance on a mountain rescue stretcher.
"We wish the casualty a speedy recovery and return to walking."
In June the rescue team helped a man in distress in Haslam Park.
And the following month they sent a team of 23 people to locate a missing 64-year-old in Rivington.
