After decades of traveling to the southern tip of the Americas, we thought it impossible to get any farther off the grid. Until we did. This adventure takes you into the impressively remote Aysén region to explore a recently opened national park, where you learn about efforts to protect vulnerable ecosystems, recover endangered species, and support local communities. You then hike across the Chile-Argentina border where there are no roads, luxuriate in a wonderfully isolated lodge set on a pristine alpine lake, and spend time in the presence of the Fitz Roy peaks.


A portion of your trip cost contributes directly to Tompkins Conservation, the group responsible for creating the new Patagonia National Park in Chile. This is just one of the organizations that GeoEx supports through our Giving Back program.
