Situated on the banks of Sungai Sepulot (Sepulot River) in the remote interior of southern Sabah, not far from the Kalimantan border, Batu Punggul is a limestone massif with amazing views over the jungle from above and with caves below. Accommodation is available at a rustic resort nearby which offers anything from a Murut longhouse or native huts (called sulap), to a hostel or guesthouses, complete with modern facilities.

Cave exploration is an exciting treat of unusual stalactites, stalagmites and bats. The Rafflesia, the world's largest flower, can be found about 25-minutes' walk from the caves. The area is also home to wild orchids. It is possible to climb to the top of the massif for panoramic views of the surrounding forest. At night, there is impressive music coming from the 'jungle symphony'...

As limestone massifs are normally found in coastal areas, the existence of Batu Punggul deep in the interior of Borneo is a source of geological wonder to scientists visiting the area.
