Kandoo's view
The full 'O' Circuit includes all the sights of the popular 'W' Circuit along with all the wonders of the quieter, northern side of the famous Torres del Paine mountain range. This adventure offers an opportunity to immerse yourself in some powerful, natural surroundings. Step away from the chaos of daily life and return to basics in an unrivalled setting. For those wishing for a trek that requires a bit more demand, the 'O' circuit packs a punch; with longer, more strenuous days than it's shorter sibling and the formidable John Gardner pass to cross. With very few hikers on this trail, you will enjoy peace and serenity and explore a unique side of Torres del Paine that many will not see.
Trip highlights

- Fill your bottle with pure, fresh water straight from nature's tap

Day 2
Arriving at Torres del Paine
This morning we will embark on our 'O' circuit trek. Our transfer will take us to the majestic Torres del Paine National Park. When we arrive at Las Torres, we will pass by the Welcome Center before starting our hike along the peaceful Serón Sector. This will take us through the Enchanted Valley, its name hailing from the unique and “enchanted” forms of granite towers standing tall amidst the shrubbery. Some of the towers yield surprising trees, perched on their crests and wedged in between, home to the impressive Condors soaring overhead. From here, we enter an old, native Lenga tree forest. Notice the trees covered by a special kind of lichen, known as “old man’s beard” (Barba de Viejo), which only grows in the purest of atmospheres. Amidst the shade of the trees lies our campsite for the night.
- Hiking time: 5 - 6 hours
- Ascent: 420 m
- Accomodation: Camping
- Meals included: Breakfast / Lunch / Dinner

Day 3
Lake Paine to Lake Dickson
This long, yet unforgettable day will take us up and down the foothills of the Paine Massif mountain range with magnificent photo opportunities along the way of towering peaks crowned with fluffy, white clouds. To reach Lake Dickson we will descend down to the shore of Lake Paine, it's beautiful, green waters the forefront to a stunning backdrop of the surrounding peaks. A gentle stroll along the flood plains of the meandering riverbed and across a section of boardwalks, brings us to a short steep climb up and back down to our remote campsite at Lake Dickson.

- Ascent: 740 m
- Accomodation: Camping
- Meals included: Breakfast / Lunch / Dinner

Day 4
Lake Dickson to Los Perros
We make the most of the shorter trekking day ahead, by waking up early and revelling in the silence on the lakeside as the clouds pass over the snowy, mountain peaks. Once we have indulged in the surrounding scenery, we will continue on our adventure, taking us through another ancient Lenga forest, home to the handsome Magellan woodpecker. On the last stretch of the trail, we break the treeline and can marvel at the Los Perros Glacier as it hangs forebodingly above a serene, grey lagoon. Tucked away in the forest overlooking the lagoon lies our campsite.
- Hiking time: 5 - 6 hours
- Ascent: 620 m
- Accomodation: Camping
- Meals included: Breakfast / Lunch / Dinner

Day 5
Los Perros to Lake Grey
Today will be the hardest but most rewarding day of the Circuit. We will leave Los Perros campsite very early and begin the uphill zigzag through the forest’s humid terrain. The path here is often very boggy and the going is slow as we step over tree roots and forest debria. The trees then deplete and give way to a barren, scree-filled landscape. We are exposed to everything the weather wishes to throw at us as we ascend a steep, scree section, passing a few false peaks, before being treated to the striking views at the top of the John Gardner Pass . We marvel at the beauty of the Southern Patagonian Icefield before beginning the unforgiving descent through the woods, followed by a long slog along an undulating balcony path to reach Lake Grey.
- Hiking time: 10 - 12 hours
- Ascent: 820 m
- Max. altitude: 1241 m
- Accomodation: Camping
- Meals included: Breakfast / Lunch / Dinner

Day 6
Lake Grey to Paine Grande
This is the part of the Circuit where the “O” meets the “W”. After a few very intense days, today we will enjoy a more relaxing walk in the foothills of the mountains, amongst Antarctic beech (ñirre), Dombey’s beech (coigüe) and the Chilean firetrees (notro), the incredible views of Mount Paine Grande, the highest peak in the region (3,050m) provide the backdrop to the day. Once we arrive at the campsite, kick-back and relax or take a leisurely walk along the peaceful shore of Lake Pehoé and marvel at it's alluring, turquoise waters.
- Hiking time: 4 hours
- Ascent: 290 m
- Accomodation: Camping

Day 7
Paine Grande to French Valley
Today is a bit of a secret killer, having already been trekking for 5 consecutive days, the ascent for today packs a hard punch. The day begins with a relatively flat hike into the Francés Valley to the Italiano refuge. From here, the path steepens and soon we are climbing up rocky terrain towards the Frances Viewpoint where we have incredible views of the glacier beyond. For those wishing to continue the challenge, and power on up to the Britanico viewpoint, we can confirm that the views are 100% worth it! The grand finale for today, finds us at a lookout over the impressive Francés Glacier and the lesser known peaks of the Paine Massif Mountain Range. We then retrace our steps back past Italiano camp and on to Frances Camp, where we will spend the night.
- Hiking time: 7 - 8 hours
- Ascent: 1050 m
- Accomodation: Camping
- Meals included: Breakfast / Lunch / Dinner

Day 8
French sector to Central Sector
We will begin today by following the weaving path of the Arriero River, which offers great places to relax and refill our bottles with fresh running water. Lake Nordenskjöld is surrounded by amazing geographical contrasts and is home to many birds, so keep a keen eye out for Condors overhead. Distracted by the beauty of the enormous summits that loom over the turquoise lake below, we begin a steep climb up to a balcony path, before dropping back down again. We then continue along the base of the magnificent Mount Almirante Nieto and its hanging glaciers before setting up camp amidst the shrubbery at the valley mouth.
- Hiking time: 5 - 6 hours
- Ascent: 745 m
- Accomodation: Camping
- Meals included: Breakfast / Lunch / Dinner

Day 9
Base Torres to Puerto Natales
We start the day with a slowly ascending hike through the Patagonian pampas that begins to steepen as we enter the Ascencio Valley, hence the name. This gradually rises to reach the Los Vientos Mountain Pass - with its spectacular, panoramic views of the surrounding landscape and lakes. We will continue hiking, past the Chileno Mountain Hostel and through a native, Lenga forest before approaching the final stretch of our adventure. The path becomes more adventurous as it weaves over rocky terrain, lined with enormous boulders. Awaiting us at the end is the awe-inspiring view of the three iconic, granite towers standing tall over the glacial lagoon. What a way to end the trek!
From here, we make a steady descent back down the valley where a transfer will take us to our hotel in Puerto Natales.- Hiking time: 8 - 9 hours

Trip information
Difficulty
This adventure is challenging. You will be trekking for 8 days, over some steep and rocky terrain, carrying all your personal equipment and sleeping bag (unless you have chosen to rent this from the campsites). You will be averaging 15km walking per day, the maximum distance covered on a single day being 20km. There may be as much as 1250m of vertical ascent and descent in a day, in particular when crossing the John Gardner pass, the wooded ascent has some boggy sections and root strewn paths that make the going slow before breaking the treeline and being exposed to all the weather can throw at you. The descent isn't any more forgiving; dropping back down through steep woodland paths on the other side. You should therefore be fit and healthy with recent experience of walking in a mountainous environment, over uneven ground for several days in a row. On steep and possibly loose ground, care should be taken to avoid slips and trips, you will definitely find walking poles useful. The weather in Patagonia is notoriously changeable and you should be prepared to walk in strong winds and heavy rain. If you have any questions about your suitability for this trip please feel free to get in touch.
Food & drink
Whilst camping in Torres del Paine National Park, your meals will be prepared at the campsites using fresh and locally sourced ingredients. You will eat in the dining room at the refuges where you will be camping for your breakfast and evening meals. Picnic lunches will also be prepared for you.
Whilst staying in the hotel in Puerto Natales, you can choose to eat at the hotel or go out and find a local restaurant.
Chilean cuisine consists mainly of meat. You will find grilled meats available everywhere including tripe, intestines and even udders. Meat aside, the cuisine is a mix of Spanish, native American and Italian influences so vegetarians can always fall back on dishes like gnocchi, pasta and pizza. In the large towns and cities, you will find all dietary requirements are catered for. You may also have the opportunity to sample “Mate”, a Paraguayan tea made from a variety of holly and typical drank from a “bombilla”.
If you have special dietary requirements please inform us when booking your adventure. We can cater for vegetarian and gluten free diets and you are welcome to bring along your own gluten free produce.
Whilst trekking, boiled water is available every morning for you to fill your bottles or bladder. We recommend you also bring a water filter or purification system to allow you to refill at refuges or springs. All drinks, including water, are your own responsibility through out the trip. We don’t recommend the use of plastic bottles which will need to be carried out and recycled.
Accommodation
Whilst in Puerto Natales we will stay in a comfortable 3-star hotel. Rooms will be double or twin with en-suite bathroom. We ensure that the hotel we use is well located to allow you to get out and explore the area.
In Torres del Paine National Park we will be camping. A 3-man tent is provided per two people along with a foam mattress. Tents will already be set up with mattresses inside when you arrive at camp. There will be shared bathrooms with flushing toilets and hot water at all sites except Camping Los Perros (cold water only). Sleeping bags are available to rent for $30, to be paid to your Tour Leader upon arrival.
Your meals will be prepared at the campsite and you will eat in the refuge 'restaurant' each morning and evening. All crockery and cutlery is provided. Packed lunches will be provided from the refuge kitchens each morning for you to take with you in your backpack.
Wifi is available at the refuges but must be bought on a pre-paid card. This can be purchased at the refuges or mini-markets at the campsites.
Luggage
Bag Weight: 15kg.
In Torres Del Paine National Park there is no vehicle access and, as we won't be using porters for this trip, you will be carrying all of your own personal equipment (from Day 2 to Day 9). For this, you will need a backpack of roughly 40-50 litres to carry with you each day. We recommend that this is no more than 14kg to ensure it is comfortable for you to wear throughout your trek. This can be used as your hand luggage on international and domestic flights. If you wish to bring another bag for items before and after the trek this can be left in secure storage at the hotel for the trekking period. We request that you do not bring a rigid suitcase as they are more difficult to transport.
Note: your backpack for trekking will be for your personal equipment and sleeping bag only and will not include tent or mattress as these will be provided at the sites.
Personal Porters: If you feel you need additional support in carrying your bag, personal porters are available to hire for $100 per day. A personal porter will be shared between up to three people and this cost will be split between you. Please inform us upon booking if you require a personal porter on your trek.
Please also be aware that on domestic flights in Argentina and Chile there is a maximum weight of 15kg on all checked luggage. If your main bag weighs more than 15kg you may be asked to pay excess luggage fees which will be your own responsibility.
How do I get there?
You will need a flight that arrives at Teniente Julio Gallardo Airport (PNT) in Puerto Natales on or before Day 1 of your itinerary. To reach Puerto Natales most will people will need to connect through Arturo Merino Benitez International Airport - Santiago (SCL).
To reach Santiago from the UK, British Airways have direct flights departing from Heathrow at 21:55 and arriving at 07:30 the next day (local time). The flight time is 14hrs. Air France offer flights from Manchester with a 2hrs 50min stop in Paris. British Airways have flights from Edinburgh with a stop of 1hrs 4min in Heathrow. Indirect flights have a total travel time of roughly 19 hours to reach Santiago.
For travellers from the USA, LATAM have a direct flight from New York to Santiago departing at 19.30 and arriving the next morning at 05:55 (local time). The flight time is 10hrs 25min. LATAM also offer direct flights from Miami with similar times. Indirect flights are available from Los Angeles, Dallas and San Francisco with LATAM, Delta and Jet Blue.
If you are changing airlines or re-checking your luggage at an airport on route, please ensure you leave a minimum of 3 hours between flights. This will account for any delays on arrival, travel time across airports (this can take longer than you think) and time taken to re-check baggage.
Travelling Responsibly
Here at Kandoo, we like to support our guests to make their travel more sustainable. As of 2025, we are offsetting the carbon on all of our trips from arrival in destination to dropping you back off at the airport. As we don't include flight travel in our trips these aren't included in our offsetting calculations, so we are providing you with the calculator below for you to do this yourselves.
Budget & change
In Chile the currency is the Chilean Peso (CLP). For the latest exchange rates please visit www.xe.com.
Few hotels and restaurants will accept US Dollars as a form of currency so it is advisable to travel with Chilean Pesos. Your guide will show you the best places to change currency at the best rate. We do not recommend the use of traveller’s cheques as they are often impractical. Bank cards are widely used for most things but please note that American Express is not commonly accepted.
In Puerto Natales, an average meal for 2 will be around $50 and a 5km taxi ride around $8. Taxis are plentiful and most drivers should have a meter, however if they don't, always remember to settle on a price before leaving. If you prefer to do it a bit cheaper then take to the streets, pretty much everywhere in Puerto Natales is less than a 20 minute walk from the town centre.
Expected budget for meals out on your trip (per person): $50
Our recommended guidance for spending budget per person in Patagonia would be between $100-150 on top of your tips. This will give you ample souvenir spending money.
Tips
Tipping is common but not mandatory and should be based on the level of service you feel you have received.
The amounts below will give you an indication of how much to tip. Please note that these amounts are for the entire group, therefore you should divide them by the total number of people in your party. You will be provided with a Tip Recommendation three weeks prior to departure with recommended tips based on the number of people in your group.
Guide: $20 US Dollars per day
Driver: $5 – $10 US Dollars per day
As an example: a guide may receive $20 per day x 8 days = $160. Divided by 10 people in the group = $16 per person.
