Climbing Mt. Trus Madi can be done in 2 to 4 days, depends on the trail you pick. There are three summit trails that lead to the highest peak of Mt. Trus Madi, i.e.: Kaingaran Trail in Tambunan Mannan Trail in Keningau Mastan Trail in Sook
The last 300m to the summit was super duper muddy! But it was also because it was raining the day before. The views were actually nicer at the viewing tower where it was higher than the summit. But apparently the official board of Mt Trusmadi was fixed here first and hence they continued to use this as the summit.
