A bushwalker caught in near-freezing temperatures will be treated for hypothermia after being found in the NSW Blue Mountains.
Justin Rebel, 20, was on Sunday afternoon found safe and well about a day after he left his friends on the Happy Valley walking trail at Mount Wilson.
Police were alerted about 8pm on Saturday when he failed to make it home.
He was found about two kilometres from where he left his friends after spending about 20 hours alone.
"It was freezing cold," his father Daniel Rebel told the Seven Network.
"I thought `geez, that kid's got nothing on,' you know he's only had a little light jacket and tracksuit pants."
He will be taken to hospital as a precautionary measure.
