Lying 12 km to the north of Mount Kinabalu, cloaked in cloud and mist, Mount Tambuyukon at 2579 meters (8462 feet) is the third highest mountain in Sabah and Malaysia. Sabah is home to Malaysia's three highest mountains. Mount Kinabalu (4095 m or 13,436 ft) is well-known as the highest point in South East Asia between the Himalayas and the mountains of New Guinea; it is famous for the sheer majesty and grandeur of its granite peaks and its immense biodiversity. Mount Trusmadi (2642m or 8669ft), the second highest peak, located in Tambunan district, and Mount Tambuyukon in Ranau district are much less frequented because of their remote location.
Mount Tambuyukon, a twin peaked mountain which, from a distance, looks like the double hump of a buffalo immersed in murky waters, lies between the boundaries of Kinabalu Park. The ascent begins at Kg. Monggis on the eastern flank, a 2-hour drive by gravel road from Ranau, best done in a sturdy 4wd vehicle. There are two trails to the summit, one from Kg. Monggis, and the other, from the Parks substation less than a km away from the village. The trail from the substation, cut recently by Sabah Parks, is more challenging because of its many ascents and descents and river crossings. Both trails coverage at 5000ft the location of the second camp. Climbers need to obtain permission from Sabah Parks to ascend this mountain.
