Situated on the banks of Sungai Sepulot (Sepulot River) in the remote interior of southern Sabah, not far from the Indonesian Kalimantan border, Batu Punggul is a limestone massif complete with caves.

Accommodation is available at a rustic Murut-style resort owned by a semi-government agency, and ranges from a Murut longhouse or native huts (called sulap), to hostel or guesthouse complete with modern facilities.

Cave exploration is fair with the usual 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 some impressive music 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 the scientists visiting the area.
