Discover more about Mylodon Cave Natural Monument

The Mylodon Cave Natural Monument, located 24 km north of Puerto Natales in the Magallanes region of Chile, offers a captivating glimpse into Patagonia's prehistoric past. The monument's centerpiece is the Cueva del Milodón (Mylodon Cave), named after the Mylodon darwini, a giant ground sloth whose remains were discovered here in 1895 by Hermann Eberhard. This discovery sparked scientific interest and revealed a wealth of paleontological and archaeological information. The cave itself is an impressive natural formation, measuring approximately 200 meters deep, 80 meters wide, and 30 meters high. It is one of several caves within the monument, which also includes the Cueva del Medio (Middle Cave) and Cueva Chica (Small Cave), each offering unique insights into the area's history. The caves are set against the backdrop of Cerro Benítez, with trails leading to viewpoints that offer panoramic vistas of the surrounding Patagonian landscape, including the Eberhard Fjord. Visitors to the Mylodon Cave Natural Monument can explore three marked trails : the Cueva Grande Trail, leading to the main cave entrance; the Mirador Trail, offering views from the cave's roof; and the Caves and Eaves Trail, which meanders through the smaller caves and the Silla del Diablo (Devil's Chair) rock formation. Inside the main cave, interpretive displays in Spanish and English detail the area's geology, paleontology, and human history. A life-size replica of the Mylodon at the cave entrance gives visitors a sense of the immense size of this extinct creature. The monument is not only a paleontological site but also a place of historical significance, with evidence of human habitation dating back as far as 6000 BC. Archaeological findings include fire-fractured rock, lithic tools, and human remains, offering insights into the lives of the early inhabitants of Patagonia. The monument is managed by the Corporación Nacional Forestal (CONAF) and was declared a Natural Monument in 1966.
