The son of a Denbigh pensioner missing in Crete says they have been walking routes he may have taken in a bid to find him.
73-year-old Arthur Jones was staying in the city of Chania, but has not been seen since June 19.
His son Jeff told ITV News much of his father's walking equipment is still in his room.
"I think a lot of people think a 73-year-old man... they sort of expect him to not be very physical, that sort of thing" he said.
"So just to get it out there that he was very fit, he would've been walking along wherever really. I mean that's the problem, we don't know."
