The O Circuit in Torres del Paine – 2021/22 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 as well as to some off-the-beaten-track parts of the park. Hiking 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 the best hikes in Patagonia.

The O circuit 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.

Besides Torres del Paine there are plenty of other incredible places to visit in Patagonia. If you don’t feel like planning your own adventure, booking bus tickets and hotels you can always join one of the exciting G-Adventure tours e.g. hiking Patagonia in-depth or End of the Earth. They have an all-inclusive Torres del Paine Full Circuit tour as well in case you don’t want to hike on your own.

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 if 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.

Suggested tours and activities in Patagonia

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 for the 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.

Campsites on the O Circuit in Torres del Paine

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. 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).

Las Torres Patagonia (Fantastico Sur) campsites are open and can be booked online. Note! Currently, it’s possible to book only pre-set tents (a more expensive camping option) at the Chileno campsite. Chileno and Los Cuernos campsites have very limited open dates. If there is no availability on your dates instead of Los Cuernos you can stay at Francés instead of Chileno at the Central campsite.

For more information check our post on the campsites in Torres del Paine. There you’ll find updated information (2021/22 hiking season) on each campsite, a map of the campsites, booking tips, and more.

Joining a group vs hiking independently

Independent trek


  • It’s much cheaper.
  • It’s more adventurous.
  • The route is well-marked and easy to follow; distances, names, altitude profiles, etc. you don’t need a guide to show you the way. 
  • In season there are many hikers on the trail even if you walk alone you won’t be lonely.


  • You have to plan the hike, book campsites, buy food, etc.
  • You’ll be carrying a heavy backpack for a week.
  • Setting a campsite by yourself; pitching tent, cooking, packing/unpacking after a long walking day. We love doing it but for some people, it’s more pain than fun.

Guided hike


  • Easy – no arrangements, bookings, gear rental etc. your tour company will do everything for you.
  • Walking with a day-pack, your luggage will be transferred from campsite to campsite.
  • No cooking, pitching tent, packing etc.


  • Quite a bit more expensive.
  • Takes away the adventurous part of the hike.

The best time for hiking

Patagonian summer from December to February is the warmest time with day temperatures between 12°C and 15°C when the night temperature is between 9°C and 12°C. November – January, and March 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.

Out of the weather point of view, February is definitely the best month for trekking in Torres del Paine. The main drawback of hiking in February – the parks are crowded, it’s the busiest month 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.

Items we love taking with on a hike

We have a detailed post on hiking and camping gear for Patagonia where you can find more information.
