O Circuit

Complete Trekking in Torres del Paine

The O Circuit represents the most demanding adventure in the park, surrounding the mountainous massif for almost 100 kilometers. On your tour, you can see from the Base Torres to the French Valley and the Grey Glacier, culminating with the view of the Southern Ice Field from the John Gardner Pass.

The journey crosses lenga forests for 7 to 10 days. This expedition, aimed at those who have already completed the "W" or seek to explore the park in depth, requires the company of a certified guide to ensure safety in the most remote sections.
