The Dientes Circuit on Navarino Island is one of the world’s southernmost trekking adventures - a remote and physically demanding circuit that few have completed. Spanning 42 kilometres (26 miles) over four days, the trail crosses the jagged Dientes de Navarino massif at the far edge of South America, offering a rare opportunity to explore one of Patagonia’s last true wilderness regions.
This rugged route follows uneven terrain across alpine valleys, lenga forests, peat bogs, and glacial lakes, reaching a high point of approximately 900 metres (2,950 feet). From the top, panoramic views open across the Beagle Channel, the towns of Puerto Williams and Ushuaia, and the distant, mythic archipelago of Cape Horn. With rapidly changing weather and minimal infrastructure, the route remains one of the most remote circuits on the continent.
This trekking adventure is designed for experienced and self-reliant hikers who are confident carrying a full pack of up to 15kg, and who are comfortable navigating in unpredictable and exposed conditions. The full circuit is weather dependent and may not always be possible - but whether completed in its entirety or adapted for conditions, this is a rare opportunity to immerse in Patagonia’s raw, untouched far south.
With 50 years of experience operating wilderness treks in remote environments, our team ensures the challenge is matched by expert support, safety, and deep regional knowledge. For those seeking a remote route with minimal crowds and maximum impact, the Dientes Circuit is Patagonia at its wildest.
