The O Circuit Torres del Paine is one of the most impressive and complete trekking routes in Chilean Patagonia. Among the best Torres del Paine National Park Tours, this iconic trail takes you through glaciers, lakes, mountains, and some of the park’s most spectacular landscapes over 8 days. In this guide, we share our experience day by day, looking the accommodations and with useful tips and information to help you prepare for the trek.

Introduction to make Torres del Paine National Park Tours

The day before starting the trek, we attended the briefing, an information session where we received our welcome kit and learned everything we needed to safely enjoy the route.

This briefing is usually held in person the afternoon before the hike begins, although there is also the option to attend it online a few days before the O Circuit Patagonia starts.

Tip: Having the right gear is key to enjoying the O Circuit Torres del Paine. At Howlanders, we’ve created a complete guide to help you choose what to wear toTorres del Paine National Park Tours. Be sure to check it out before packing your backpack!

With our backpacks ready and all the information in hand, we headed to the Puerto Natales bus station. At 6:45 a.m., we were already there, ready to start the adventure. The bus departs at 7:00 a.m. toward Torres del Paine National Park, specifically to Laguna Amarga Entrance, one of the park’s main access points.

Once there, we showed our park ticket to the CONAF rangers and boarded a connecting shuttle to the Welcome Center. From there, day 1 of the O Circuit begins, hiking from Central Lodge to Serón Campsite. Let the trek begin!

O Circuit Day 1: Central Lodge – Serón Campsite

• Distance: 8.7 mi / 14 km
• Moving time: 3 h 20 min
• Estimated total duration: 4 h 30 min
• Elevation gain: 984 ft / 300 m
• Elevation loss: 866 ft / 264 m
• Difficulty: Moderate

The first stage of the O Circuit Torres del Paine begins with a gentle climb along a trail that crosses the Patagonian forest. The elevation gain is gradual during the first few miles, making it an easy way to settle into the rhythm of the trek. As you continue hiking, the scenery slowly changes as the route approaches the Paine River.

Once you reach this area, the landscape opens up completely. The forest gives way to wide grasslands with open views, and the trail follows the river for several miles. Along the way, it’s common to see free-roaming horses and fields covered with wildflowers, adding a special charm to this quieter section of the O Circuit Patagonia.

The day ends at Serón Sector, a small and cozy campsite on the O Circuit. There is no lodge here, but the campground has restrooms, hot showers, and a shared shelter that serves as a dining area during meals and a meeting point for hikers throughout the day.

O Circuit Day 2: Serón Campsite – Dickson Sector

• Distance: 11.8 mi / 19 km
• Moving time: 4 h 45 min
• Estimated total duration: 6 h 30 min
• Elevation gain: 1,181 ft / 360 m
• Elevation loss: 1,083 ft / 330 m
• Difficulty: Moderate
• Watch in Wikiloc

Day 2 of the O Circuit Patagonia starts with breakfast at Serón Campsite before beginning the hike at 8:00 a.m. The first section of the trail is mostly flat, following the river for about 2.5 miles / 4 km and continuing through landscapes similar to the previous day. Gradually, the terrain begins to climb toward Lake Paine, with a short but steep ascent.

Once at the top, the first panoramic views of Lake Paine appear. The trail follows the lake for several miles before descending into a denser forest area. Along the way, hikers pass a CONAF checkpoint where reservations are verified. In this section of the trail, there are wooden boardwalks used to cross wet and muddy areas. This stretch is more enclosed and has a noticeable presence of mosquitoes, so most hikers keep a steady pace until reaching more open areas.

After hiking approximately 11.8 miles / 19 km, the day ends at Dickson Sector, one of the most complete campsites on the O Circuit Torres del Paine, with a lodge, campground, and basic services. From here, you can walk to the lakeshore for views of Dickson Glacier and the Southern Patagonian Ice Field, one of the highlights of the day. The evening ends in a great atmosphere at the lodge, enjoying the complimentary welcome drink at the bar and sharing stories with other travelers.

O Circuit Day 3: Dickson Sector – Los Perros Campsite

• Distance: 7.8 mi / 12.5 km
• Moving time: 3 h 30 min
• Estimated total duration: 4 h 30 min
• Elevation gain: 1,411 ft / 430 m
• Elevation loss: 246 ft / 75 m
• Difficulty: Moderate
• Watch in Wikiloc

Day 3 of the O Circuit Patagonia is shorter in distance, but still quite demanding due to the terrain and trail conditions. The route goes from Dickson Sector to Los Perros Campsite, crossing one of the wettest areas of Torres del Paine National Park, with a high presence of mosquitoes, especially in the dense forest sections.

The trail climbs steadily throughout the day with very few descents, making the effort constant from start to finish. After the first few miles, hikers reach a viewpoint with panoramic views. From there, the hike continues into an increasingly wild landscape, where the vegetation becomes less dense and the terrain rockier.

As the trail progresses, the scenery begins to change. Temperatures drop, mosquitoes disappear, and the first signs of the glacier environment start to appear. The highlight of the day is reaching the Los Perros Glacier area, visible from the moraine, with an impressive glacial lagoon as the reward for the effort.

The day ends at Los Perros Campsite, the most basic campground on the O Circuit Torres del Paine, where full services are not always available, so bringing your own food is recommended. Even so, the campsite has a small store and the option to rent camping gas, allowing hikers to prepare something hot before resting. This is a key stop before taking on the most challenging stage of the trek: the John Gardner Pass.

And if you’re planning your Patagonia trekking adventure, don’t forget the essentials: bug spray, extra food, and a camera with enough battery for that spectacular glacier view..

H2: O Circuit Day 4: Los Perros Campsite – Grey Sector

• Distance: 10.6 mi / 17 km
• Moving time: 6 h 20 min
• Estimated duration: 9 h 20 min
• Elevation gain: 2,927 ft / 892 m
• Elevation loss: 4,518 ft / 1,377 m
• Difficulty: High
• Watch in Wikiloc

Day 4 of the O Circuit Torres del Paine is the most challenging stage. Departure from Los Perros Campsite is strictly controlled by the campground staff, and hikers must leave before 7:00 a.m. This is for safety due to the difficulty of the route and the demanding terrain conditions.

The first section of the trail crosses a very wet and technical forest, with constant mud, exposed roots, and steep climbs all the way to John Gardner Pass. As the ascent continues, the terrain becomes more unpredictable. Depending on the season, snow is common near the top of the pass, making gaiters highly recommended. This part of the hike requires continuous physical effort and extra caution.

The most breathtaking moment comes after crossing the pass, when the full scale of Grey Glacier suddenly appears. The landscape is completely dominated by ice, deep crevasses, and massive glacier tongues. From here, the route begins a long and highly technical descent, probably the hardest part of the day. The descent feels slow and physically exhausting, with fatigue building in the legs while the terrain demands constant focus to avoid slipping, especially after rain.

During the descent, hikers reach El Paso Campsite, where it is mandatory to check in with CONAF before continuing. After stopping for lunch and recovering some energy, the trail continues along Grey Glacier, crossing suspension bridges and passing spectacular viewpoints overlooking the glacier.

Finally, the day ends at Grey Sector, where the atmosphere changes. After such a demanding stage, there is a strong sense of relief and accomplishment among hikers arriving at the lodge.

Tips for the Los Perros – Grey Stage. Torres del Paine National Park Tours

• Bring breakfast and lunch prepared from previous stages.
• Leave no later than 7:00 a.m.
• Gaiters are highly recommended if there is snow on the pass.
• Take your time on the descent, especially after rain.
• Make sure you have enough battery and storage space on your camera. You won’t want to miss the photos of Grey Glacier.

O Circuit Day 5: Grey Sector – Paine Grande Sector

• Distance: 7 mi / 11.25 km
• Moving time: 3 h
• Estimated duration: 3 h 20 min
• Elevation gain: 1,115 ft / 340 m
• Elevation loss: 1,214 ft / 370 m
• Difficulty: Moderate

Today, the O Circuit Torres del Paine changes the pace of the trek with a completely different experience: a kayaking activity in front of the massive Grey Glacier wall. Although there was also the option to do the glacier ice hike, we chose kayaking instead.

The day starts early as usual, with breakfast at 8:00 a.m. followed by a transfer to Grey Beach, the meeting point for the activity. Paddling so close to a glacier wall rising more than 100 feet / 30 meters above the water creates a sense of scale that is difficult to describe. Every movement of the water reminds you of the power of Patagonia’s nature.

After the activity, we returned to Grey Lodge to begin the hike toward Paine Grande. This is one of the shortest stages of the O Circuit Patagonia, allowing hikers to move at a relaxed pace and enjoy the scenery. We took advantage of the extra time at the lodge to rest and have lunch before starting the trail.

The route follows the shoreline of Grey Lake along a gentle trail, although it remains constantly exposed to the strong Patagonian wind. Little by little, the glacier views begin to disappear as the landscape opens toward Lake Pehoé.

Arriving at Paine Grande marks the end of the adventure for many hikers completing the W Trek, is a much busier and more accessible area of the park. We spent the night at the lodge, with the wind as the main character, waiting for the next stage of the O Circuit Torres del Paine toward Los Cuernos.

O Circuit Day 6: Paine Grande Sector – Francés Sector

• Total distance: 17.1 mi / 27.5 km
• Moving time: 7 h
• Estimated total duration: 10 h
• Elevation gain: 3,228 ft / 984 m
• Elevation loss: 3,091 ft / 942 m
• Difficulty: Moderate to high
• Watch in Wikiloc

Day 6 of the O Circuit Patagonia is one of the most flexible and spectacular stages of the trek. Hikers can either go directly from Paine Grande to Francés Sector or extend the day by exploring the French Valley. In our case, we left our backpacks at the CONAF station near Italiano Campsite so we could hike lighter into the valley.

The first goal is the French Viewpoint, reached after a steady climb of about 1.9 miles / 3 km with roughly 984 ft / 300 m of elevation gain. From there, the views are incredible, with Lake Nordenskjöld becoming the main highlight of the landscape, sometimes even more striking than the glaciers themselves.

For those continuing farther, the trail climbs toward the British Viewpoint, a more demanding section with an additional 2.5 miles / 4 km uphill and around 820 ft / 250 m of elevation gain. Since the route is out and back, this section requires an extra physical effort. In total, exploring the French Valley adds around 8.7 miles / 14 km and more than 1,804 ft / 550 m of elevation gain, surrounded by steep mountains and increasingly dramatic scenery.

After descending, hikers collect their backpacks at Italiano Campsite and begin the final part of the day’s hike. The last section follows Lake Nordenskjöld through an open landscape heavily exposed to the Patagonian wind, before reaching Cuernos Sector, where the day comes to an end.

Tips for Grande – Francés Stage Torres del Paine National Park Tours

• Bring a small daypack for the French Valley hike.
• Start early if you want enough time to reach the British Viewpoint.
• Take care of your knees — the descent from the valley is long.
• Protect yourself from the wind with a good windbreaker or technical jacket.

O Circuit Day 7: Francés Sector – Central Sector

• Distance: 8.3 mi / 13.3 km
• Moving time: 3 h 20 min
• Estimated total duration: 4 h 20 min
• Elevation gain: 1,115 ft / 340 m
• Elevation loss: 938 ft / 286 m
• Difficulty: Moderate to easy
• Watch in Wikiloc

Day 7 of the O Circuit Patagonia is a much calmer stage after the intensity of the previous day. The route goes from Los Cuernos Sector to Central Sector, following an easy to moderate trail that is perfect for recovering energy before the final major challenge of the trek.

This day starts at a relaxed pace, with most of the elevation gain concentrated in the first few miles, where hikers get great views of Lake Nordenskjöld. Today’s trail is comfortable and easy to follow, crossing small bridges and passing through open landscapes that feel much calmer than previous stages, especially when the strong Patagonian wind is absent.

Toward the end of the hike, the trail splits between the route leading to Chileno Sector and the one heading to Central Sector, also known as Central Lodge. This area is one of the main access points to start Torres del Paine National Park tours, together with Paine Grande, and offers a large capacity of accommodations and services for hikers.

Upon arrival, the atmosphere feels busier and more organized, with larger facilities where travelers rest and prepare for the final stage of the circuit. The day ends in a comfortable setting focused on recovery before the big challenge ahead: the hike to Base Torres.

O Circuit Day 8: Central Sector – Base Torres

• Distance: 13.7 mi / 22 km
• Moving time: 6 h 12 min
• Estimated total duration: 9 h 4 min
• Elevation gain: 3,517 ft / 1,072 m
• Elevation loss: 3,517 ft / 1,072 m
• Difficulty: Moderate to high
• Watch in Wikiloc

Day 8 of the O Circuit Patagonia is the final stage of the trek and one of the most iconic parts of the entire route: the hike to Base Torres Viewpoint. After an early breakfast at Central Sector, we started the trail focused on the last major challenge of the circuit.

The first section climbs steadily toward Windy Pass, gaining around 1,476 ft / 450 m of elevation over just 2.5 miles / 4 km in a completely exposed area where strong wind is usually the biggest challenge. From there, the trail continues toward Chileno Sector and enters a lenga forest that provides shade and a short break before the final climb.

From the CONAF ranger station begins the most demanding part of the day: a climb of more than 1,640 ft / 500 m in only 0.9 miles / 1.5 km over rocky and technical terrain. There is no defined trail here, but rather a chaotic field of large boulders that forces hikers to scramble uphill with constant effort until reaching Base Torres Viewpoint. The reward is one of the most spectacular views in Patagonia: the three granite towers reflected in the glacial lagoon.

After enjoying the viewpoint, we started the descent back down, once again passing through Chileno Sector and Central Sector, where we picked up our backpacks. From there, we walked to the Welcome Center and took the transport back to Puerto Natales.
