Everything You Need to Know about the O Circuit in Patagonia

If you are reading this blog post, it is because you are interested in living a remarkable adventure, a daring trip to Torres del Paine to hike one of the most famous hiking circuits in the world. Together with the W, the O Circuit attracts hundreds of travelers from different corners of the planet, and you can be one of them.

What is the difference between the W and the O circuits? Both routes get their names from the trail’s layout. The O is a route that runs the entire perimeter of The Park, where its final and initial point is the same. It is the longest route in Torres del Paine National Park. Due to its longer distance, the trail feels more intimate with nature because it has fewer hikers than the W. There will be various moments when you will be alone on this extensive route (93.2 km), which takes between 7 or 8 days.

The “O” circuit includes the “W,” the first in an extension of the second, so you will see the most iconic landscapes of the Torres del Paine National Park while hiking on it. Also, if altitude concerns you, you will be at most 1,200 meters above sea level during the expedition. 

Now, what will you see on the Circuit O hike?

Serón

In Serón, you’ll see a field full of daisies that horses use like an esplanade, a serene place where they spend winter. In this area, you will be able to see the eastern part of the Paine Massif, and in the distance, with clear skies, you will see the Andes Mountains. Serón is one of the quietest places on the circuit. It’s your ideal checkpoint before continuing with your adventure.

Dickson Glacier

At Dickson Glacier, you will have an incomparable view, where mountains, ice, and forests come together in a single panorama. This glacier originates in the Southern Ice Fields. During the last few decades, Dickson Glacier has experienced significant melt, causing an expansion of the Dickson Lake that borders this majestic place.

Dickson Lake

After a challenging climb, you will see a lake that rises from the South Ice Fields and empties into the Paine River. This extraordinary place results from the meeting of the Dickson, Cubo, and Frías glaciers. In 1998, the drawdown of Dickson led to an expansion of the lake, which now spans 17 km (10.5 mi) long and crosses the border of Chile and Argentina.

Los Perros Glacier

This hanging glacier comes from the Olguín mountain range and not from Campos de Hielo Sur, which explains its name of Olguín Glacier on the south side. This glacier has experienced the most significant melt in the last 20 years.

Gray Glacier

The famous Gray Glacier is the largest in the Torres del Paine National Park.

There are three bridges here that people stop for a photo op, making it one of the most remembered areas by our visitors. Taking a picture here is a moment you’ll treasure forever. You can take a boat ride, kayak tour, or ice hiking excursion to see this impressive ice formation.

Paine Grande

This sector has one of the most splendid views of the park. Here, you can witness the western sector of Cerro Paine Grande. The mountain peak you can see from here is Punta Bariloche. You will also be able to make out Lake Pehoé with its turquoise color, and if the weather conditions are favorable, you will see the horns of the Paine.

Hiking in Paine Grande, you will find many Chilean Firebushes or Notros with their red flowers. Nearer to the lake, you can see pairs of Caiquenes and Hualas, which are local waterfowl. Walking through the grass, you can find the Calafate bush with its famous berry we use in some of our dishes and specialty cocktails.

When it comes to natural beauty, these three mountains share the admiration of thousands of hikers who have toured the park.

A 700-meter-high granite massif crosses the formation, giving this natural beauty a framework.
