Day 1

1 hour flight / 4-5 hours hiking (7.4 miles) / night at laguna salto campsite (BL-D).

From Punta Arenas fly by light aircraft to Puerto Williams. During your flight, take in the imposing glaciers and rock faces of the Darwin Ranges, the famous Magallanes Strait, Tierra del Fuego’s snaking canals and the imposing Beagle Channel. You won’t have to wait long to immerse yourself in these dramatic southern landscapes – 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 where views of the Beagle Canal, Puerto Williams, Valle Ukika and Cerro Robalo (912m) reward you. Continue on to today’s campsite at Laguna Salto, accompanied by the serrated Los Dientes as you trek.

Day 2

4-5 hours hiking (5.6 miles) / night at campsite laguna escondida (B-BL-D).

Today’s route takes you through several 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, complete with views of the Cape Horn archipelago. Today’s breath-catching tableaus don’t end here. Continue on to Paso Los Dientes, with dramatic views of the highest peak on Isla Navarino, Picacho Diente (1118m), scenic lagoons to the north and south. Laster, Cerro Gabriel’s summit shows itself en route to our campsite at Laguna Escondida.

Day 3

3-4 hour hiking (5 miles) / night at camping laguna martillo (B-BL-D).

Shrub and native ñirre forests accompany you to Paso Ventarrón (696m), a windy pass that lets trekkers peer through the window towards Isla Navarino’s untouched side: the unexplored wild mountains behind the Dientes de Navarino. From here, we’ll trek to Paso Guerrico before circling Laguna Hermosa and taking in the arresting views of Cerro Clem.

Day 4

3-5 hours hiking (6.5 miles) / night at camping laguna los guanacos (B-BL-D).

Begin today by circling Laguna Martillo and rock hopping close to the 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, at 859m the highest point in your trek 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 our campsite. Relax, steady your feet and take your time to descend.

Day 5

2-3 hours hiking (8.6 miles) / night at lakutaia lodge (B-BL-D).

From Laguna Los Guanacos, 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. Your lodgings are just a short distance from the end of the trail. Settle in and enjoy a farewell dinner and night of restoring slumber.

Day 6

1 hour flight (B).

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