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 as well as to some off-the-beaten-track parts of the park. Backpacking in Torres del Paine you get an opportunity 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.

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 of Torres del Paine with the remote parts of the park.
How hard is the O Circuit in Patagonia?
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-meters 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 the O trek 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 Central campsite to Serón to Dickson etc.).
How to buy entrance tickets to Torres del Paine?
According to the official website you have to buy your entrance tickets to Torres del Paine online. It used to be different you could pay the fee at the entrance. I’m not sure if it’s still possible for this reason I’d recommend rather booking your tickets online. We’re planning to visit Torres del Paine again this year (2022) and will update you on that.
Tickets should be booked at least 24 hours before your visit.
The entrance fee for the O Circuit (more than 3 days in the park) is 49$US for adults, and children under 12 years old – free.
You can show your tickets on the screen of your mobile phone or print them.
Torres del Paine park rules
In the 2022/23 hiking season the O circuit is open from 1st 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 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), it’s said to be of good quality. We didn’t use any filters or purification.
You can get more information on Torres del Paine at a daily free talk at the Erratic Rock hostel/gear shop. The talk is usually at 3 pm.
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.
Travel insurance. The O-circuit is a multi-day trek with some parts through remote and difficult to access areas of the National park so having travel insurance for this route is a good idea. Any outdoor activity involves the risk of getting an injury, losing or breaking gear, and other unexpected situations that can spoil your trek. It’s always advisable to have travel insurance that can cover you in case something goes wrong. We recommend our partners World Nomads. They work all over the world and specialize in outdoor activities like hiking. You can buy travel insurance online while traveling it takes a couple of minutes. Their policy is very flexible it can cover the entire trip or only the hiking part of it. Get a quote right now! Note! Always make sure you carefully read the Terms and Conditions part.
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 O trek?
The campsites on the O-trek belong to three different companies. CONAF (the National Forest Corporation) – free campsites Paso and Italiano. Vertice Patagonia paid campsites: Dickson, Los Perros, Grey, and Paine Grande. Las Torres Patagonia (Fantástico Sur) paid campsites: Central, Serrón, Francés, Los Cuernos, and Chileno. Paid campsites have better facilities and are easier to book. They have more camping spots than the free campsites.
There is a new online booking service (Booking Patagonia) that you can use to book all the campsites. We haven’t used them yet but it seems that the prices of the campsites and other types of accommodation are the same as on the Vertice and Las Torres websites. The service is recommended on the official CONAF website so I believe it’s legit, it’s just very new and I couldn’t find any reviews.
|CONAF campsites||Vertice Patagonia campsites||Las Torres Patagonia campsites|
|Paine Grande||Los Cuernos|
The campsites in Torres del Paine can be booked online through the CONAF, 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.
The two free CONAF campsites (Paso, Italiano) can’t be booked online there is no information on when (and if) they’ll reopen. The CONAF office in Puerto Natales, Manuel Baquedano st. 847. You can inquire about campsites there. Even when the free campsites were open it was very difficult to make a reservation. For these reasons, our suggested itinerary for the O Circuit includes only paid campsites.
All Vertice Patagonia campsites are open and can be booked through their website. Important! For the O Circuit, it’s impossible to book a separate campsite with Vertice Patagonia. It’s only possible to make a reservation for 3 or 4 campsites together. For e.g. you can book Dickson, Los Perros, and Grey or Dickson, Los Perros, Grey, and Paine Grande. It means that even if the free campsite Paso (between Los Perros and Grey) is available for booking it doesn’t make sense to stay there. It’s better to walk from Los Perros to the Grey campsite (you have to book and pay for both anyway). In 2022/23 hiking season Dickson and Los Perros on the Circuit are open from 1st November.
Las Torres Patagonia (Fantastico Sur) campsites are open and can be booked online. According to their website in 2022, Cuernos and Seron campsites will be open and available for booking from 1st November (the same day as the O Circuit). Chileno is a very popular campsite because it’s the closest to the Mirador Las Torres. I’d strongly recommend booking it a couple of months in advance, especially during the peak season. The rest campsites (Central, Chileno, and Frances) open in September.
For more information check our post on the campsites in Torres del Paine. There you’ll find updated information (2022/23 hiking season) on each campsite, a map of the campsites, booking tips, and more.

The best time for hiking the O circuit in Patagonia
The O Circuit in the 2022/23 season is open from 1st November still 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.
Places to stay in Puerto Natales
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.
