Gunung Kinabalu, as it is known in Malay, is more than the highest thing on the world's third largest island. And it is more than scenery. Mt Kinabalu is ubiquitous in Sabah to the point of being inextricable. It graces the state's flag and is a constant presence at the edge of your eyes, catching the clouds and shading the valleys. It is only when you give the mountain your full attention that you realise how special this peak, the region's biggest tourist attraction, truly is.
The 4095m peak of Mt Kinabalu may not be a Himalayan sky-poker, but Malaysia's first Unesco World Heritage Site is by no means an easy jaunt. The main trail up is essentially a very long walk up a very steep hill, past alpine jungle and sunlit moonscapes, with a little scrabbling thrown in for good measure. If you don't feel up to reaching the mountain top, its base has some worthy attractions, including a large network of nature trails.
That said, the main detriment to climbing is not the physical challenge, but the cost. Things are expensive within Mt Kinabalu National Park. Bottled water costs four or five times what it goes for in KK and Sutera Sanctuary Lodges has a monopoly on accommodation. You'll have to decide if you want to accept these fees, because they are basically the cost of climbing the mountain.
Amazingly, the mountain is still growing: researchers have found it increases in height by about 5mm a year. On a clear day you can see the Philippines from the summit; usually, though, the mountain is thoroughly wreathed in fog by midmorning.
