Mylodon Cave Natural Monument


Visit caves once inhabited by a giant sloth and follow trails leading to lookouts and magnificent views of the Patagonian countryside.

Cueva del Milodón is a series of natural caves cut into the Patagonian landscape. Discover stories of prehistoric creatures and the hunters who settled in South America’s barren Patagonia region. Walk along marked trails to observation points, which provide views of a breathtaking wilderness.

Learn about the first world-wide recognition for Cueva del Milodón in 1895, when German pioneer Eberhard Hermann found the skin of a huge animal. Scientists later confirmed that it was the fur of a mylodon, a giant sloth that roamed South America over 10,000 years ago.

Explore the park’s four caves and three trails. Start by taking the trail to Mylodon Cave, the largest, which measures 660 feet (200 meters) deep and 260 feet (80 meters) wide. Experts believe that it was a popular hunting ground for the earliest inhabitants of Patagonia. Take a selfie photo next to the life-size replica of the massive sloth.

Go to the Devil’s Chair, an imposing rock formation said by some to be the throne of the mylodon others claim that it’s the chair of the devil himself. It marks the start of the Caves and Eaves Trail. Peek inside the Middle Cave, where archaeologists have found traces of human life dating back 11,000 years. Go to the humble Small Cave and admire the surrounding ancient native forest.

Climb Viewpoint Trail to enjoy sweeping views from Viewpoint Cave on the top of the hill. Spot the channels of Eberhard Fjord and the remains of ancient glacial lakes. Snow-capped mountain peaks rise out of the distance.

The caves are a 30-minute drive north from Puerto Natales. Get here most easily via taxi or rented car. Travel agencies in Puerto Natales offer guided tours, often as part of an excursion to Torres del Paine.

Cueva del Milodón is open daily and has an admission fee. Bring your own food and make use of the designated picnic areas located on the trails. Download a map and an audio guide in English from the cave’s official website.
