From Punta Arenas fly via light aircraft to Puerto Williams. During your flight, take in the drama of the Darwin Range’s glaciers and rock faces, the Magallanes Strait, Tierra del Fuego’s snaking canals and the imposing Beagle Canal. You won’t have to wait long to immerse yourself in Tierra del Fuego’s natural drama – your first day of trekking begins in a few short hours after orientation in Puerto Williams. Today, you’ll cross sloping beech forests to the summit of Cerro Bandera to reward yourself with views of the Beagle Canal, Puerto Williams, Valle Ukika, and Cerro Robalo (912m). Continue on to today’s campsite at Laguna Salto, accompanied by the serrated Los Dientes as you trek.

Today’s route takes you through several mountain passes in the Circuit, starting with the small rocky pass at Paso Primero (705m), where year-round snow greets visitors at the entrance to the high valley. The trail follows creeks, loose rock, and lagoons, and provides no end of pause-worthy moments to take in the interplay of blue-green hued lagoons and imposing peaks. The next pass is Paso Australia, today’s highest point at 776m/805m, though the breath-catching tableaus from the top are not the day’s last. We’ll continue on to Paso Los Dientes, with dramatic views of the highest peak on Isla Navarino, Picacho Diente (1118m), and descend to our next camp at the base of Mount Bettinelli. After setting up camp, we hike to Bettinelli’s summit for more fantastic views of the Cape Horn archipelago.

Shrub and native ñirre forests accompany you to Paso Ventarrón (696m), a blustery pass letting trekkers peer through the window to see Isla Navarino’s untouched side: the unexplored wild mountains behind the Dientes de Navarino. Continue on to Paso Guerrico before circling Laguna Hermosa and taking in the arresting views of Cerro Clem. Tonight, we will make camp at Laguna Martillo.

Begin today by circling Laguna Martillo and rock hopping on shores of Laguna Rocallosa. After descending towards some smaller lagoons, you’ll enter a section of sharply-inclined woods followed by a rocky ascent. This is the route to Paso Virginia, the highest point in your trek at 859m and keeper of arresting views of the Beagle Canal, Darwin Range, and Laguna Los Guanacos. After crossing the pass, you’ll begin a steep descent towards Laguna Los Guanacos. Relax, steady your feet and descend slowly.

From Laguna Los Guancos descend towards its sister-lagoon, Laguna Las Guanacas. A river-crossing will take you to the entrance to some woods huddled at the base of rocky cliffs. Later, the route will cross Calafate berry-covered slopes and lead you once again to views of the Beagle Channel. Our final stretch today takes us through the Omora Ethnobotanical Park, an investigation and conservation center dedicated to research into the region’s native flora. Here, we’ll participate in a “miniature forest” experience, using magnifying glasses to peer into the teeny tiny world of lichen, liverworts, and moss. After arriving in Puerto Williams, stretch your legs as you explore the town. In the evening, enjoy a farewell dinner and night of restoring slumber at a guesthouse.

Tuck in to a well-deserved breakfast and congratulate yourself – you’ve completed the challenging Dientes de Navarino circuit! After check out, your return flight is waiting for you to take you back to Punta Arenas.
