Guide to trekking on the Torres del Paine Circuit 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.

Circuit Map O
This circuit, known as the "O" because of the approximate shape it follows around the park's towers , offers a longer and more demanding route. Along the way, travelers will have the opportunity to experience the grandeur of the landscapes at their finest: from ancient forests to imposing glaciers and mountain peaks that defy imagination.

Technical specifications of Circuit O
- Duration : 7-8 days
- Distance : 93.2km
- Technical difficulty : Medium – high
- Physical difficulty : High
- Trails : Marked
- Maximum altitude : 1200 meters above sea level
- Elevation difference : +6517 m -6572 m
When to go and weather
The best time to hike Circuit O is from November to March , when temperatures range between 5°C and 20°C. However, keep in mind that Patagonian winds and rain are frequent, making it feel colder. It's important to avoid winter , as the road is closed during that season.

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.

Attractive and challenging John Gardner Pass
The O Circuit, being longer than the popular W Circuit, leads adventurers to discover unique places such as Dickson Lake, Los Perros Glacier, Grey Glacier and the challenging John Gardner Pass , among other majestic sites.
Considered the most challenging section in the entire park, the John Gardner Pass reaches an altitude of 1,200 meters above sea level. With a 600-meter elevation gain over 4 kilometers uphill and another 4 kilometers downhill, this section will test your endurance .

Why choose O over W
The O Circuit option will immerse you in a wilder and less crowded experience compared to the W Circuit , which becomes very busy during peak season. Few adventurers attempt the entire O Circuit, guaranteeing a more peaceful experience for over a week of trekking.
Discover the true essence of Chilean Patagonia through the challenging yet rewarding Circuito O in Torres del Paine, an experience that will be etched in your memory forever. Every step will be worth it .
