Visiting San Telmo and La Boca on our last day at Buenos Aires concluded our 16-day journey to the world's end. With an open mind and keen eyes, we will never feel bored of travelling.

Our first day at Buenos Aires were not all joys. Only after we immersed ourselves into the tango music and dance after the night fell, we began to comprehend the magic of this city.

Bounded by the Chilean border at the Argentina side, Tierra del Fuego National Park is the southernmost national park in the world. Although the scenery is not as dramatic as Torres del Paine, the park offers nice view of lakes, mountains and the Beagle Channel.

Ushuaia, the southernmost city in the world, has only one main street. It is the gateway to explore the Antarctic Ocean and Tierra del Fuego.
