Located 30 Kms. from Puerto Natales. A short path that ends in the imposing cave of 30 Mts. of height and 200 Mts. of depth, in the slope of the mount Benitez.

In 1896 the scientific world was fascinated by the discovery in this cave of the skin, bones and other parts of an extinct animal, the Milodon (Mylodon Darwini).Scientists originally believed the remains to be fresh, indicating that the animal still existed. But later tests proved that the remains were thousands of years old.

The milodon, a very large herbivore, is believed to have died out at the end of the Pleistocene era.
