Hito Limítrofe Laguna Larga

This beautiful trek leads you through the most exuberant and practically unexplored forest in the area, until reaching the milestone which marks the border between Argentina and Chile, skirting the hidden Laguna Larga with spectacular views of the Lago Del Desierto and the Fitz Roy massif from the North.


Navigation from Punta Sur to Punta Norte del Lago del Desierto

At 10.00 a.m. the boat sets sail navigating across the lake, reaching Punta Norte in just under an hour. Once in Punta Norte, you have about 6 hours to do this trek, and board the boat at 5.30 p.m. back to Punta Sur.

The trail begins just behind the National Gendarmerie Post, where the forest begins next to a small stream.

Lenga native forest

The trail immediately begins to ascend, and as you gain altitude you will discover the landscape behind you: the Lago Del Desierto in its full extension, framed by the Del Bosque range to the east and the Vespignani range with its hanging glaciers to the west.

After about half an hour of ascent, the path begins to decrease and the trail enters an overwhelming Lenga forest really silent and very little visited.

The trail goes across some basic tree trunk bridges over the small stream coming from the Larga lagoon.

More or less an hour from the start, there is a “mallín” (muddy land due to moisture saturation) that must be surrounded on the right, and the trail always continues in the same direction North to enter again the last stretch of the forest while the path gains a little more altitude.

Larga lagoon

After a few minutes you can see from the top the beautiful Larga lagoon hidden in this virgin forest.

The last stretch of the trek passes by some old abandoned facilities of the National Gendarmerie and a few steps from there, it is the “Hito Limítrofe” the milestone that marks the dividing line of waters that defines the border with Chile. From this point at almost 40 km away you can admire the granitic mass of the Fitz Roy Mount that continues to stand out in the landscape towards the South.
