(CNN) — Before Christianity and Islam became the dominant religions of the island of Borneo, animist beliefs dictated that when a person died, their spirit rose to the peak of Mount Kinabalu.
At 4,095 meters above sea level, it's one of the highest mountains in Southeast Asia.
Today, UNESCO-listed Mount Kinabalu National Park is one of the most popular tourist attractions in the state of Sabah, in Malaysian Borneo, with visitors needing to book two to three months in advance to secure one of 196 daily allocated hiking permits.
Though Sabah is developing at pace, villagers living at the foothills of Mount Kinabalu continue to perform animist rituals to appease spirits residing at the cloud-ringed peak so no harm comes to those who scale it.
The above images were taken on the rock-strewn 8.7-kilometer trail to the summit with Evan Conrad, a guide with Amazing Borneo Tours who first climbed Mount Kinabalu 20 years ago.
Porters earn 128 Malaysian Ringgit ($40) for two days' work on Mount Kinabalu.
"I've climbed the mountains maybe 100 times," Conrad said.
"But I never get bored of it. Every time I see something new that excites me, and the view at sunrise is never, ever the same."
There are multiple options for those wanting to hit the summit, ranging from from one-day to two-night climbs.
Pros recommend beginners do the three-day, two-night option. It allows them to acclimatize to the altitude.
Only the super-fit should try to get to the summit in a day.
Guides and permits are required by law.
From Malaysia's capital of Kuala Lumpur, a number of flights to Sabah capital Kota Kinabalu are available.
Flight time is about two and a half hours.
The drive from Kota Kinabalu to Mount Kinabalu takes about two hours.
