Located 24 kilometres north of Puerto Natales, Cueva del Milodón is a Natural Monument comprising three caverns and a rock formation known as the Devil’s Chair. The main cavern, situated 150 metres above sea level, reaches 30 metres in height, 80 metres in width, and 200 metres in depth.
Its scientific importance stems from the discovery in 1895 of remains of the mylodon (Mylodon darwini), a large herbivorous mammal that became extinct at the end of the Pleistocene. In addition to its historical and palaeontological value, the surrounding area is notable for its landscape and biodiversity, where steppe and forest ecosystems coexist alongside native flora such as ñire, calafate, and romerillo. Animal life is abundant, particularly bird species.
