The Torres del Paine Circuit, or “O-Trek,” is one of the world’s most iconic and rewarding multi-day hikes - circling the entire Paine Massif through the heart of Chilean Patagonia. This full circuit offers a far more remote and immersive experience than the popular W-Trek, taking you deep into the park’s lesser-visited valleys, glacial basins, and high alpine passes.
The trek begins through grasslands and forests before climbing into a dramatic alpine world of granite peaks, glaciers, and turquoise lakes. A key highlight is the John Garner Pass, with stunning views of Grey Glacier and the Southern Patagonian Ice Cap. From there, the trail descends to Lago Grey and joins the W Trek, revealing new perspectives of the towers. Side hikes into the French and Ascensio Valleys lead to a final, unforgettable ascent to the base of the Torres del Paine.
This challenging yet accessible trek is ideal for experienced hikers with solid fitness, seeking a truly immersive Patagonian adventure. With established campsites, thoughtfully managed logistics, and a limited trekking season from November to March, early booking is essential to secure your place on this unforgettable circuit through one of South America’s most spectacular landscapes.
