Batu Punggul, Sabah
Not many travellers make it down here, deep in the Borneo interior. Their loss, because Batu Punggul, an incredible rock formation that juts like a limestone knife into the air, and more importantly the primary jungle that surrounds it, is one of the most stunning sites on an island full of jaw-droppers. To get here you will travel via tea-and-mud rivers, crossing under the canopies of ancient-growth trees. The reward: a sharptooth rock that presents a physical challenge to climbers, and deep travel Zen satisfaction for dedicated explorers.
