One of the most inhospitable places I have ever been to, Cabo Polonio sits on the tip of a moon-sliver shaped peninsula that extends into the Atlantic Ocean. The only access is by walking through the dunes or 4×4 vehicles. There is an important light house and a natural reserve of sea lions, the biggest in the world.
My last adventure was an expedition to Chilean and Argentinean Patagonia, with a group of 18 people guided by eco-friendly walkers. It was an 18-day walk through 130 km in Los Glaciares National Park, Tierra del Fuego National Park and Torres del Paine National Park, in Chile. We reached the cities of El Calafate, El Chaltén and Ushuaia.
