After decades of traveling to the southern tip of the Americas, we thought it impossible to get any farther off the grid in this part of the world. Until we did. This adventure takes us into the impressively remote Aysén region to explore a new national park, to hike across the Chile-Argentina border where there are no roads, and to luxuriate in a wonderfully isolated, welcoming lodge set on a pristine alpine lake.

After meeting in Santiago, the Chilean capital, and flying to the Aysén, we journey overland to Patagonia National Park. Based from its elegant, intimate eco-lodge, we go for awe-inspiring hikes and learn from our friends at Conservación Patagónica about efforts to protect vulnerable ecosystems, recover endangered species, and support local communities.

Next we follow the lonely Carretera Austral (or Southernmost Highway) to the frontier town of Lago O’Higgins, a kick to explore, then boat across its namesake glacial lake to start an intrepid hike across the border. After two rewarding nights by Lago del Desierto, we make our way by boat, vehicle, and foot to the charming town of El Chaltén, where we ramble among peaks of the famous Fitz Roy range. A flight to Buenos Aires brings us back to civilization.

If you'd like to discover more of Patagonia, ask about our tempting Torres del Paine extension. And if you’d like more time in Santiago or Buenos Aires, we’re happy to make the arrangements.
