It is considered the third-highest mountain in the country with height at 2,579 metres (8,461 ft),[1][2] lying north of the highest Mount Kinabalu.

[3] The glaciated summit plateaus and Pleistocene glacial tills of the Kinabalu area including similar deposits near to Mount Tambuyukon indicate that the summits of Tambuyukon, Kinabalu and possibly Trusmadi were significantly higher than other parts of the Crocker Range by the Pleistocene.

[5] The mountain supports a wide range of unique flora and fauna, including a number of pitcher plant species of the genus Nepenthes.

[10] There are two climbing trails towards the mountain summit, one from Monggis village and the other from the Sabah Parks substation in the same village, both located in the Kota Marudu district with permission from the park authority needing to be obtained before the climbing.

[11] The mountain is considered one of Sabah's ecotourism destinations, albeit minorly.
