Frequently Asked Questions
How to Plan to Hike the O-Circuit in Torres Del Paine
First, determine the dates you want to visit from November – March. Then determine how many days you want to do the hike in; most people do the circuit in 5-8 days. If you want a shorter hike, check out my guide for how to hike the W-Trek, which is the bottom half of the O-Circuit (see map above)
Next, decide which campsites you want to stay at. The website where you can book the campsite reservations includes pre configured routes, which takes the work out of creating an itinerary.
Note: You will not need to stay at every campsite to complete the O-Circuit, so determine the distances you want to hike each day and plan accordingly. The O-Circuit in Torres del Paine is hiked counterclockwise.
Then, at least 3 months in advance, book your campsites at Booking Patagonia. To ensure you get the dates you want, it is advised to secure your bookings as soon as they open for the upcoming season
When to go
November – March
This period is the Southern Hemisphere’s summer, and offers the most favorable weather conditions with milder temperatures and longer daylight hours. December to February is considered the high season when the park experiences the warmest temperatures, making it more comfortable for trekking.
During this time, you can expect temperatures ranging from 50 to 60 degrees Fahrenheit (10 to 15 degrees Celsius) on average. The trails are generally drier, and the days are longer, providing ample daylight for hiking.
It’s essential to note that while summer is the ideal time, Torres del Paine’s weather can be unpredictable, and conditions may vary. Therefore, hikers should be prepared for changes in weather and be equipped with appropriate gear for varying conditions. When I was there, I got sunburned during the first two days and then got snowed on during day three. The wind was fierce and cold pretty much every day.
How to book reservations/ permits
Reservations are required to camp in the park. They fill up very quickly, so it is advised to book them as soon as they open reservations for the upcoming season.
When booking your reservations, you can choose between camping (in your own tent or a rented tent), or staying in a refugio (bed in a shared dorm). It is cheaper to bring your own gear, but tents and sleeping bags can be rented. The tents are already set up at each campsite, so you wouldn’t be carrying it with you and setting it up every day- you would simply show up and when you check in, they will tell you which tent is yours.
Historically, it was a nightmare booking the campsites because they were owned by a couple different companies. The websites were confusing and you had to line up the dates and hope that you booked them correctly. Luckily, as of 2023, the campsites on the O-Circuit can be booked online together through Booking Patagonia. If you want to book them separately (I don’t know why you would…) you can book them on Vertice Patagonia and Las Torres Patagonia.
Costs
The cheapest option is to bring all of your own gear and cook your own food. A 7-day trek will cost about $300 per person.
The price for a camping reservation (with your own gear) is between $10-$15 USD per person per night. Meals in restaurants range from $15 – $40.
Gear rental costs (per person, per night):
Tent (2 persons): $40
Sleeping bag: $25
Sleeping Pad: $12
Full board (breakfast, box lunch, and dinner): $80 – $100
Separate Meals: breakfast $25, dinner $40, lunchbox $25.
If you stay at fully-equipped campsites (tent, sleeping bag, sleeping mat) you’ll pay around $100 per person per night. Dorms with bunk beds are available at some campsites for around $60 per person. The campsites have small stores where you can buy snacks, drinks, and other essentials. The larger campsites have full restaurants where you can order things like burgers and beer.

The entrance fee to Torres del Paine (for 3+ days) is $49 for adults, and free for children under 12 years old.
The park fee must be paid at least 24 hours in advance online, AND you need the QR code saved to your phone. They don’t accept payments at the park entrance gates. There is no cell service or WIFI at the entrance of the park.
How to Get to the Park and Start the Hike
You will fly into and be based out of Puerto Natales. This is the nearest town to Torres del Paine National Park.
- Take a bus from Puerto Natales to Torres del Paine
All buses leave from the bus terminal in Puerto Natales. The ticket costs $28 (including return) and the journey takes 2-3 hours. Arrive 15-30 minutes before your scheduled departure. There are a few different bus companies, but they are all essentially the same and leave at 7am, 7:30am, and 2:30pm. During the high season, it’s recommended to buy your bus tickets at least one day in advance. Tickets for the bus company Bus-Sur can be booked online whereas the others can be purchased at the terminal or your accommodation.
- Get off the bus at the Laguna Amarga.
- Get on another bus (10 minutes) to the Welcome Center, where it is required to start the hike. This bus costs about $6. From there, it’s a 9k (5.6-mile) hike to reach the Serón campground.
If this seems confusing, don’t worry- the rangers and bus drivers are very friendly and are used to people doing this trek. As long as you know where you’re starting/going, they will help you and point you in the right direction.
Torres del Paine Park Rules
- Campsites have to be booked in advance. Have the booking confirmation printed or on your cell phone.
- You can only camp at designated campsites.
- Fires are not allowed anywhere in the park.
- Cooking and stoves are allowed. However, all cooking must be done in designated cooking areas/ kitchens.
- It’s required to have a passport and a migration card (you get it entering Chile) with you on the trek.
Other Important Information
- Puerto Natales is the best place to be based before and after the hike. The town has many hotels, campsites, restaurants, shops, and gear rental places.
- Safe drinking water can be found all over the park. A lot of people don’t even bother using any filters or purification systems on the trek.
- Get more information about Torres del Paine
- You will need Chilean pesos on you for the park as nowhere accepts cards.
What to Pack
Bring a base layer, mid layer, thermal layer (warm coat), and a rain protection layer (waterproof shell, both top and pants).
The weather is unpredictable and inconsistent. Some days you could be in a t-shirt getting sunburned, and the next you could be wearing a hat and mittens because it’s snowing. Inclement weather aside, the wind is fierce, making even sunny weather seem uncomfortably chilly. Waterproof shells also help protect against the wind, and you will be warmer by layering it on top. Bringing clothing that you can layer to suit all types of weather will keep you comfortable and your pack lighter.
Trekking poles are an essential piece of safety equipment and I don’t hike without them. They are especially useful if you have a heavy pack on because they help maintain your balance.
If you plan on bringing your own tent, a tent that is highly rated for wind is essential. To this day, this was the strongest wind I have ever experienced, and I am amazed at how well my tent held up. For links to all the gear I use, check out my backpacking gear list.
Bring a waterproof pack cover because it is likely to rain or snow, even in the summer.
As with any long hiking excursion, packing lighter is the way to go. You do not need to bring a whole cook set, you do not need to bring a lot of toiletries. I have a personal rule that for any trips under 7 days, I do not shower. This means I do not bring any toiletries or a towel, saving both weight and space. I bring a small package of baby wipes to clean myself.
You will not get lost. The trail is clearly marked and there is a steady stream of people.
My honest opinion of the trek
The landscapes are stunning, and I am glad I did it. However, I go backpacking to be out in nature experiencing peace and solitude. This trail is so crowded that it’s impossible to be alone.
Unfortunately, the volume of visitors really detracted from my experience. Other hikers not being aware of trail etiquette (letting people pass, etc.) or camp etiquette (dont shine your headlights into people’s tents at night, etc.) was a continual nuisance.
This hike is great for people who are not comfortable being alone in nature or are looking to meet other people. If you are an experienced backpacker, this will likely feel too mainstream and commercialized for you.
Conclusion
The O-Circuit is a beautiful hike located in one of the most beautiful and rugged places in the world. The jagged mountain peaks and bright blue lakes are a reminder of how wild and incredible nature is. If you are looking for a wonderful but challenging outdoor adventure, the O-Circuit is sure to be an experience you won’t forget. Be sure to book your campsite reservations several months in advance and pack as light as you. Bring layers and waterproof gear and don’t forget your camera!
