Kinabalu

A 4,095-metre peak in the Crocker Range on the island of Borneo, in the Malaysian state of Sabah. Mount Kinabalu is the highest mountain in Southeast Asia between the Himalayan foothills and the Indonesian archipelago. The peak is geologically distinct from the volcanic mountains that dominate the region — Kinabalu is a granitic batholith, a massive intrusion of igneous rock that emerged through the surrounding sedimentary terrain over the past ten million years. The summit complex consists of multiple jagged granite peaks, with Low's Peak the highest point. The mountain is sacred to the Kadazan-Dusun people of Sabah, who hold that the spirits of the dead reside on the upper mountain.

The first recorded ascent came in 1851 by Sir Hugh Low, the British colonial administrator after whom the highest summit is named. Low's expedition reached the summit plateau but did not climb to the highest point of the granite spires; the precise summit was first reached in 1888 by John Whitehead, a British naturalist working in the region. The technical difficulty of the standard route to the summit plateau is modest — the climb is essentially a long uphill walk on established trails. The granite spires above the plateau require some scrambling on smooth rock, with fixed ropes installed on the steepest sections.

The route from Kinabalu Park headquarters at 1,866 metres to Low's Peak takes typically two days, with an overnight stay at the Laban Rata resthouse at 3,272 metres. Climbers leave the resthouse before dawn for the summit attempt, aiming to reach the top before the daily cloud build-up obscures the views. The fatality rate is low, though deaths have resulted from falls on the granite slabs in wet conditions and from hypothermia during the cold pre-dawn summit pushes. In 2015, an earthquake centred on the mountain killed 18 climbers when granite blocks collapsed on the upper route.

The peak is climbed by approximately 40,000 summit attempts per year, more than any other 4000-metre mountain in Southeast Asia. The combination of accessibility, modest technical difficulty, and the cultural and ecological significance of Kinabalu Park has made the mountain a primary destination for the regional climbing community. The summit, when reached, sits within sight of the South China Sea on one side and the Borneo interior on the other.
