The organisation said climbing the mountain was not notable enough to merit a world record.
But Wynn had the idea that, if he was going to go all the way to Indonesia to climb a mountain, he might as well raise some money for his favourite charity the SPCA.
The charity’s Legacies Supporter Care officer Louise Dilly said Wynn has been an SPCA supporter for decades.
“Even though Guinness World Records don’t recognise climbing Kinabalu as a record, we still think that climbing the mountain at 85 years old is an incredible achievement,” said Dilly.
Mount Kinabalu stands at 4095 metres above sea level and is the highest mountain between the Himalayas and New Guinea.
It derives its name from the Kadazan word “Aki Nabalu”, meaning “the revered place of the dead”.
Wynn told the Herald he encountered orangutans in the bush on Sabah.
“I did a few bush treks with the guide and we saw some in their natural environment,” he said.
“We were driving along an unsealed road in the bush and saw an orangutan on the side of the road so we bailed out of the truck.
“It was three metres away, but didn’t pay attention to us.”
After finishing the hike, he wasn’t affected by the altitude sickness but was naturally a bit tired.
“My legs were a bit sore.”
However, he said there is a big difference between looking at the mountain far away to looking at it close up.
