Puerto Natales is a port city on the Señoret Channel in Chile’s southern Patagonia. It is the gateway to Torres del Paine National Park to the northwest and the port for boats touring the Patagonian fjords. The Municipal Historical Museum in the city centre exhibits artefacts from the region's indigenous people. To the north, it is the vast Cueva del Milodón (Mylodon Cave), once inhabited by the prehistoric ground sloth mylodons.
