Dientes de Navarino Backpacking Trek

We’ll pick you up from your accommodation in Punta Arenas and transfer you to the airport for your flight to Puerto Williams, where your adventure on Navarino Island begins. After a brief trip briefing and gear check, we’ll head to the Río Róbalo water intake, where our trekking expedition begins.

The trail winds through a beautiful lenga forest before climbing steadily to 600 meters (1,970 ft) above sea level. At the summit, a large Chilean flag marks a spectacular viewpoint overlooking Puerto Williams, the Beagle Channel, and the mountains of Tierra del Fuego.

From there, we’ll continue along the forest’s edge, following the Río Róbalo Valley until we reach Laguna del Salto. Surrounded by pristine wilderness, we’ll set up our first campsite and enjoy a peaceful evening immersed in the untouched landscapes of Navarino Island before continuing the expedition the following day.

After breakfast and breaking camp, we’ll begin our trek around 9:00 a.m. We’ll continue along the trail toward Australia Pass, skirting the impressive Dientes de Navarino massif. As we gain elevation, we’ll be rewarded with breathtaking views over the southern side of Navarino Island and the Wollaston Islands, located at the northern edge of the Cape Horn Archipelago—a landscape that truly captures the feeling of standing at the end of the world.

After taking in this spectacular scenery, we’ll continue our journey through some of the island’s most remote landscapes before reaching, around 7:00 p.m., a suitable campsite near either Laguna de los Dientes or Laguna Escondida, depending on trail conditions. There, we’ll set up camp and enjoy a well-earned rest before the next day’s adventure.

After enjoying a good breakfast, we’ll break camp and continue our expedition toward Laguna Martillo. Today’s journey will take us through some of the most remote and challenging landscapes of the circuit, crossing valleys, wind-shaped forests, and mountain passes that define the wild character of Navarino Island.

We’ll begin by following the left side of Laguna Escondida, walking along a short section of the river before entering a valley that leads us toward Ventarrón Pass. From there, we’ll continue ascending through the valley until reaching Guerrico Pass, following trails that wind between large boulders and small forests of vegetation adapted to the harsh conditions of the southern wilderness.

After crossing the pass, we’ll skirt Laguna Hermosa until reaching its outlet. We’ll then continue northward, zigzagging through the windswept forest until reaching Laguna Martillo after approximately five hours of trekking. In this privileged setting, we’ll set up camp and enjoy another night surrounded by the pristine nature of this remote territory.

After a hearty breakfast and breaking camp, we begin our hike around 9:00 a.m. The trail takes us through a fairytale landscape, with native shrub and ñirre forests, crystal-clear lagoons, and the Dientes de Navarino massif as a dramatic backdrop.

We will ascend to Paso Ventarrón (696 m / 2,195 ft), a windy pass that allows us to look through its natural “window” and admire the untouched side of Navarino Island: wild, still-unexplored mountains stretching beyond the Dientes de Navarino. We will continue to Paso Guerrico, approaching the beautiful Valle Guerrico, enjoying the southern flora and rugged landscapes that define this remote region.

We will have lunch before continuing to a suitable camping area near Laguna Martillo or Laguna Zeta, where we will set up camp around 7:00 p.m., surrounded by the tranquility and majesty of this extreme landscape.

After breakfast, we’ll begin the final stage of our expedition, descending toward the Beagle Channel. The trail crosses a forest shaped by the presence of beavers before entering a taller forest as we follow the valley’s slopes northward.

As we gradually lose elevation, the landscape begins to transform. We’ll continue descending through zigzagging trails among calafate bushes until reaching the coast, where the facilities of the MacLean fishing company will come into view, marking the end of our journey through the Dientes de Navarino.

From there, we’ll transfer to Errante Ecolodge, where we can rest, enjoy the comforts of the lodge, and share a well-deserved farewell dinner, celebrating the end of an unforgettable adventure in one of the most remote and wild corners of the planet.

After enjoying breakfast at your accommodation, we’ll check out and transfer to Puerto Williams Airport to board your flight to Punta Arenas. Depending on flight availability, the schedule may be adjusted accordingly.

From here, we’ll transfer you to your accommodation, marking the end of our unforgettable expedition through the Dientes de Navarino Circuit. A journey that has taken you through some of the most remote, challenging, and spectacular landscapes of Chile’s southernmost region.
