Guide to trekking on the Torres del Paine Circuit O

Circuito O

Among the contrasts and natural wonders that Chile holds in its treasure chest, the most valuable for many is Torres del Paine National Park , the great jewel of Patagonia that has conquered the adventurous hearts of travelers and trekking lovers around the world, especially those who dared to explore the O Circuit .

The majesty of its landscapes and the diversity of its flora and fauna make Torres del Paine an unmissable destination for those seeking unique experiences in nature. The park, declared a Biosphere Reserve by UNESCO, is famous for its imposing rock formations, majestic glaciers, turquoise lakes, extensive forests, and hiking trails, the W Trek being the most renowned.

However, there is another, lesser-known but equally impressive route: the O Circuit . It's a challenge for trekking enthusiasts seeking a more extreme and less crowded experience. While the W Circuit remains the most popular route in the industry, the O Circuit offers a unique adventure, allowing explorers to immerse themselves in the vastness and serenity of Patagonia's wilderness .

Despite its physical demands, the Circuito O rewards intrepid hikers with unparalleled views and an intimate connection with nature . Its less-traveled paths allow walkers to immerse themselves in a silence broken only by the wind and the natural sounds of the surroundings.

Time required to travel the O

At 93.2 km long, the O Circuit requires a minimum of 7 or 8 days to complete . Physical difficulty and weather conditions can affect your progress, and keep in mind that there are fewer amenities than on the W Circuit. Plan your itinerary considering these factors, and remember that some adventures on the O Circuit are also scaled back.

The importance of tents in the O Circuit

In the northern part of the Paine massif, you'll only find one refuge, Dickson. Given the distance between Grey Refuge and Dickson Refuge (30.7 km), it's essential to carry a tent and spend the nights at the Paso, Perros, or Serón campsites . Keep in mind that there are tour packages that include accommodation in refuges or campsites and provide tents.
