A six-hour rescue operation took place on a 3,000ft Snowdonia peak on Thursday night after a man was found unconscious in his tent.
A party of rescuers from Aberdyfi Search and Rescue Team attended the scene on Cader Idris, near Dolgellau.
Low cloud meant a coastguard rescue helicopter was unable to reach the man, who is in his 50s and from the Manchester area.
Instead he was carried down a long and difficult route, known as the Minffordd steps, by stretcher.
The man was taken by ambulance crew to Bronglais Hospital.
