Dubbed as the third highest mountain in Sabah and Malaysia at 2,579m, Mount Tambuyukon is a twin peaked mountain that lies between the boundaries of Kinabalu Park, 12KM north of Mount Kinabalu. It may be the third highest mountain, however the climb would be challenging due to the terrain and distance to the trail.
The climb begins from Monggis Substation which has camping ground facilities as well as bunk beds and facilities such as toilets and kitchen. It is a 2 hour drive from Ranau to reach Monggis Substation and best with 4WD. For the whole journey, it will probably take you 5D/4N to conquer Mt. Tambuyukon.
Mt. Tambuyukon lies between the boundaries of Kinabalu Park, so you may expect to see amazing selection of the flora and fauna in Sabah. Nepenthes edwarsiana and Nepenthes villosa (endemic to Mt. Kinabalu and Mt. Tambuykon) can easily be seen here.
Climbers need to obtain permission from Sabah Parks to ascend this mountain.
