  • Trip Highlight

    You’ll constantly be rewarded with views of Patagonia’s varied landscapes

As indicated by the name, the Torres del Paine O trek is a loop encircling the mighty Cordillera del Paine Mountains within Patagonia’s Torres del Paine National Park. Although it does intertwine with the more popular W trek, the Full or O Circuit as it’s also known doesn’t receive as many tourists. As such, it offers hikers a chance to explore this heaven-on-earth type of setting without hordes of people. Opting for this trek allows you to discover the raw beauty of Chilean spell-binding landscapes. Here, you’ll find it all—winding rivers, glistening glaciers flowing into mirror-like lakes, various lush forests, abundant wildlife, and the highest summit of the Cordillera Paine, Cerro Paine Grande (2,884 m/9,462 ft). Although quite demanding, the iconic hike to Mirador Base Torres will reward you with surreal views of three majestic granite peaks looming over a turquoise glacial lake and serve as a perfect ending to a thrilling adventure.

Day 4: Sector Grey

Even though you won’t be trekking as much as you will on some other days, today will probably be the most exhausting, but also the most spectacular day of your trip. This is because today’s hike contains slippery roads, swampy terrain, as well as steep climbs and descents. The departure from Los Perros is very early. The first part of the way is through swampy land and a steep and long climb to Paso John Garner. You’ll get to witness one of the huge tongues of the Southern Ice Field. Start the long descent between rocks, to continue skirting the Grey Glacier, which will be your silent companion all the way to Lake Grey. After arriving at the site “El Paso”, cross two suspension bridges that pass over huge gorges and admire the fantastic views of the Grey glacier. You’ll spend the night in Sector Grey.
Meals: Breakfast, lunch, dinner
Accommodation: Camping or refugio
Hiking distance: 6.8 miles (11 km)
Hiking time: 4.5 hrs

Here you can have lunch and revel in the scenic views. Keep going towards the French Sector with Lake Pehoé on your right and another face of Cerro Paine Grande on your left.

Keep hiking to reach the Chilean Refuge and then enter a forest of lengas and reach La Morrena. This is where the most difficult part of the trekking begins. After 45 minutes of ascending along a rocky path, you’ll get to the spectacular Mirador Base Torres. Here you can witness the beautiful South (2,850 m / 9,350 ft), Central (2,800 m / 9,185 ft), and North (2,600 m / 8,530 ft) Towers.

Brett Schlesinger about Unu Raymi Expeditions on Unu Raymi Expeditions’ website

This was a trip that I’ll never forget! James @ Unu Raymi was incredibly helpful in getting me prepared, answering my questions, and organizing the travel. In fact, he went out of his way to schedule the trek in between two other organized expeditions to accommodate my desire to travel. My guide, Eduardo, was extremely knowledgeable, technically proficient, and extremely helpful in teaching me all of the skills necessary, such that I could have been able to do the whole trek myself! The service and equipment were all top notch – especially traveling solo, I never once felt unsafe, and if anything felt completely welcome and at home. I am excited to travel with them again in the future and you should be too!
