Mitchell, at home in Silvan in the Yarra Ranges, thanked "everyone so much" for keeping an eye out for his father.
"This is the best news that could ever happen," he said.
A friend of his, who was with him, added, "And a happy Father's Day".
"Yeah, happy Father's Day," Mitchell said, laughing.
Mitchell, 25, said his father was "fine" and had walked into the police station with police.
It is believed he was dehydrated, but physically OK.

A smiling Ken Tromp had earlier told media outside the police station "everything is going really well", but the family did not want to make any further comment.
Police confirmed Mr Tromp had been cleared by a medical assessor from Albury Wodonga Health and was safe and well. He did not need to be taken to hospital.

It is still unknown why the 51-year-old fled his Silvan home with his wife and three adult children last Monday.
He had not been spotted in three days since he abandoned his car and ran into Merriwa Park on Wednesday.

Despite speculation that the family suffered a shared delusional disorder before and during their "technology-free" road trip, Mitchell told Fairfax Media there were no recent or current psychological diagnoses in his family.
Paranoia over financial affairs – or that someone was trying to steal their money – is believed to be the catalyst for triggering the family crisis.

The paranoia built up to a point where Mark and his wife, Jacoba, became terrified someone was coming after them before making the ill-fated decision to leave the family home in Silvan last Monday.
Monbulk sergeant Mark Knight, who works with Mr Tromp's brother and knows the family, said no one was after the family and they were not being followed.
Police have not found evidence their money was being targeted by a thief.
Sergeant Knight said previously there were no diagnosed mental health conditions and there is no evidence of drug taking or drug psychosis.
The family have no debts and their businesses – an earth-moving company and berry farm – are successful.
His wife Jacoba and eldest daughter Riana remain in hospital in Goulburn being assessed by mental health practitioners. Relatives have travelled to Goulburn to be with them.
In a previous appeal to the public on Thursday, Mitchell said he had never seen anything like what he saw happen in his family.
"It's really hard to explain or put a word on it but they were just fearing for their lives and then they decided to flee," he said.
"It was a build-up of different, normal, everyday events – just pressure – and it slowly got worse as the days went by."
Mark and Jacoba Tromp were seen together at a Wangaratta shopping centre on Wednesday.
The next sighting came when a Wangaratta couple reported the Tromp's grey Peugeot station wagon following them around the streets about 10pm the same day.
When they stopped in Ely Street, they saw Mr Tromp get out of the car, run past Christopher Robin Kindergarten and into Merriwa Park.
Police were earlier investigating three break-ins on Thursday at a horse club, football club and the general store around Milawa and Oxley.
The back door had been pushed open at each premises and food was taken from one.
It is not known if Mr Tromp was responsible and may have been trying to get supplies, but his family had been hopeful it was him.
