The O Circuit in Torres del Paine – 2024/25 season

The O circuit in Torres del Paine National Park is an incredible hiking adventure. The scenery on the route is fantastic: turquoise lakes, waterfalls, bizarre mountains, stunning viewpoints, a massive glacier, and diverse wildlife. The route takes hikers to the highlights and off-the-beaten-track parts of the park. Backpacking in Torres del Paine you get a chance to explore one of the most beautiful places in South America. I could easily say that the O trek is one of our favorite long-distance treks in Patagonia.

The route overview

• Distance – 120 km/74 miles.
• Required number of days – 7-8 days.
• Starting and finishing point – Central campsite (Laguna Amarga entrance).
• Highest point – John Gardner pass – 1220m/4000ft.

What is the O Circuit?

The O trek is a circular hiking route around the Cordillera del Paine in Torres del Paine National Park in Chilean Patagonia. The route includes the W trek and a remote route through the backside of the park. The circuit connects the popular areas and the remote parts of the park.

How difficult is the route?

It’s a moderately difficult trekking route that goes through some remote areas of Torres del Paine National Park. The most challenging part of the O route is a 900-meter ascent to John Gardner Pass. It’s not a high-altitude technical route only for experienced hikers but being in good physical shape and having previous hiking experience is advisable. On average, you walk 6-8 hours a day with a backpack.

How long is the O circuit?

The total distance of the O Circuit in Torres del Paine is 120 km/70 miles. You need between 7 and 9 days to complete the route.

Where does it start?

The O circuit starts at Hotel Las Torres (Central campsite). The nearest park entrance is Laguna Amarga. The circuit can be walked only counterclockwise (from the Central campsite to Serón to Dickson etc.).

Can you hike without a guide?

Yes, you can do the O circuit in Torres del Paine independently without a guide.

How to buy entrance tickets to Torres del Paine?

According to the official website, trekkers have to buy their tickets to Torres del Paine online.

The entrance fee for the O Circuit (more than 3 days in the park) is 44 500 CLP/50$US for adults and children over 12 years old. Children under 12 years old – free.

You can show your ticket on the screen of your mobile phone or print it.

Besides your entrance ticket, they check your accommodation bookings. You must have a spot booked for every night on the trek without it you won’t be allowed to do the O circuit.

Torres del Paine Park rules

In the 2024/25 hiking season, the O circuit is open from the 1st of November. 

Hikers are allowed to camp only at designated campsites. Wild camping is not allowed in the park.

Campsites on the route must be booked beforehand.

Take a printed/digital booking confirmation, a passport, and a migration card with you on the trek.

Open fires are not allowed in Torres del Paine.

Using a camping stove is only allowed at the campsites.

Drinking water can be found throughout the park (rivers, creeks, streams), and it’s said to be of good quality. We didn’t use any filters or purification. 

If you’re looking for adventurous and off-the-beaten-track things to do in Patagonia traveling the Carretera Austral might be just what you need. The southern route through Chilean Patagonia offers many exciting activities in the most beautiful corners of the region.

If you like hiking and wilderness you might enjoy exploring trekking routes in El Chalten, Argentina. There are several day hikes and multi-day routes that can be done independently.

How to book the campsites on the trek?

The campsites on the O-trek belong to two different companies. Vertice Patagonia paid campsites: Dickson, Los Perros, Grey, and Paine Grande. Las Torres Patagonia paid campsites: Central, Serrón, Francés, Los Cuernos, and Chileno. Vertice Patagonia campsites are significantly cheaper than the Las Torres Patagonia campsites.

There used to be free campsites run by CONAF (the National Forest Corporation) but they were closed down and never reopened. There is no information if they’ll be open again. For this reason, our suggested itinerary for the O Circuit includes only paid campsites.

Vertice Patagonia campsites	Las Torres Patagonia campsites
Dickson	Central
Los Perros	Serón
Grey	Francés
Paine Grande	Los Cuernos
	Chileno

The campsites in Torres del Paine can be booked online through Vertice Patagonia, and Las Torres Patagonia websites. You have to have your booking confirmation printed or on your mobile to show at the park entrance.

Vertice Patagonia

All Vertice Patagonia campsites are open for online booking. Important! On the O Circuit, you can’t book only Dickson, Perros, or Grey. These three campsites have to be booked together. In the 2024/25 hiking season

• Dickson campsite is open from 2nd November
• Los Perros – from 3rd November
• Grey – from 4th November
• Paine Grande – from 1st October

The circuit is open from the 1st of November but on the first night, you stay at the Seron campsite (Las Torres Patagonia).

Las Torres Patagonia

As of 27th of August Las Torres Patagonia campsites are open for online booking. According to their website in 2024

• Frances – from 15th September
• Cuernos – from 1st November

The best time for hiking Torres del Paine

In the 2024/25 season, the O circuit is open from 1st November to 31st March. You have a 5-month period to decide when is the best time to visit Torres del Paine.

Patagonian summer from December to February is the warmest time with maximum day temperatures averaging 20°C and night temperatures between 9°C and 12°C. November, December, and January get quite a lot of wind –  the biggest problem for hiking and camping in Patagonia. February is the least windy summer month. It’s the same with rain out of all summer months February gets the least rainfall.

From the weather point of view, February is one of the best months for trekking in Torres del Paine. The main drawback of hiking in February – the parks are crowded, it’s one of the busiest months for the park with most visitors coming here. It means you must book campsites long in advance to make sure you get a spot on planned dates. If the campsites on the route are fully booked you can do one of the alternative multi-day treks in Patagonia e.g. Cerro Castillo Circuit or hike to O’Higgins Glacier if you want to explore a more off-the-beaten-path route.

Where to buy dehydrated meals for the O circuit?

If you like taking dehydrated meals on your multi-day hikes you can buy them in Puerto Natales. There is a gear rental shop called Rental Natales. They sell dehydrated meals of the Back Country Cuisine brand. The price is US$16 per meal (two servings). They have quite a variety of meals.

You might find dried fruit and nuts in Unimarc and Super Mix supermarkets.

Where to stay before the trek?

Puerto Natales is probably the best place to be based before and after the trek. It’s the closest town to the park, tourist infrastructure here is quite good – many hotels and hostels, a couple of gear shops, rental places, restaurants, tour companies, and one or two supermarkets. You can get there by bus or hitchhiking from different places in Patagonia.

In Puerto Natales, you can find hotels, hostels, campsites, restaurants, supermarkets, gear rental places, pharmacies, ATMs, and an information office.

• Budget | Hostel 53 Sur | Xalpen B&B |
• Middle price | Hostal Treehouse Patagonia | Wild Hostel |
• Luxury | Toore Patagonia | Weskar Lodge |
