Five search and rescue teams scrambled to action after a family with two young children got lost on Kinder Scout.
More than 80 rescuers battled harsh weather and tough terrain after a 999 call.
The family had set off from Edale on Easter Sunday.
They raised the alarm after getting lost but their mobile phone signal failed before useful information on their location could be passed on. This sparked a major search involving teams from Edale, Buxton, Kinder and Glossop.
An Edale spokesman said: “Two search and rescue dogs were also called. The weather had been deteriorating throughout the evening with visibility of less than 20 metres, and the wind was gusting up to 30mph.
“By the early hours of Bank Holiday Monday no trace of the missing family had been found and concerns were growing for their welfare.
“After more than six hours searching, team members were tiring due to the weather and underfoot conditions, so a fifth team from Derby was called.”
At 3am, the Glossop team’s dog handler found the family on the northern edge of Kinder Scout.
The cold and wet family was able to walk to safety after being given food and hot drinks.
n Edale mountain rescue team helped a climber who had a serious fall on Rivelin Edge on Sunday.
The 27-year-old had fallen about five metres and suffered a severe head injury and multiple spinal fractures. She was taken to Northern General Hospital.
