Yendegaia National Park is in Tierra del Fuego in the Magallanes y la Antártica Chilena Region of Chile and contains 150,612 ha (372,170 acres) of mountainous terrain and Valdivian temperate rain forest.

[5] The park is located south of the Azopardo River and stretches from the Darwin Range to the Argentine border and from the Beagle Channel to Fagnago Lake.

The new park protects the last remaining sub-Antarctic beech forest, one of Earth's largest remnants of the Gondwana super continent dating back 180 million years ago.

The nearest urban area is the town of Porvenir in Chile, although the Argentinian city of Ushuaia is also nearby.

[7] Classified as subpolar oceanic climate, the weather in this region is variable and often inhospitable with heavy rain and regularly overcast skies.
