From Punta Arenas (Chile), we flew to Ushuaia (Argentina): the capital of Tierra del Fuego, the southern most city in the world, and the primary tourist gateway to Antarctica. We stayed in a very nice and friendly B&B

The main purpose of this destination was a walk on Perito Morino Glacier and going to El Chalten, (a village inside National Park Los Glaciares).
Hiking around El Chalten and seeing Fitz Roy was the highlight of our entire trip.
