High atop the Malaysian mountain Gunung Mulu is an impressive alien landscape made of sharp rock spires that rise up out of the surrounding jungle like spikes of angry earth. 

The climb to the Pinnacle of Gunung Mulu is gruelling and dangerous, so much so that the national park is sometimes used by the Malaysian Army for training. However, those who are daring enough to make the trek to the top of the mountain will be rewarded with one of the most unique and stunning vistas in the world.

The tall stone spikes known as the Pinnacles of Gunung Mulu are stark karst formations that were created as the soft limestone eroded away across millennia. Hidden so far up the mountain, the formations are relatively untouched by humankind and the only people to be seen for miles are other pilgrims to the bizarre bit of topography.
