Don’t forget about travel insurance!

The O-circuit is a multi-day trek with some parts through remote and difficult to access areas of the National park – getting 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. Of course, my travel insurance didn’t help me to recover it but it did cover the cost of new gear and clothes.

Out of many insurance companies, we recommend World Nomads, they work all over the world and specialize in outdoor activities like hiking. Torres del Paine is one of the top destinations World Nomads cover which means they work with local companies quite a lot and will be able to resolve a case without any complications. Another great thing about World Nomads is that you can buy an insurance policy online while traveling (it takes a couple of minutes), their policy is very flexible it can cover the whole period of your trip or only the hiking part of it, even if it’s just one or two days.

Note! Always make sure you carefully read the Terms and Conditions part.

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.

Suggested tours and activities in Patagonia

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

You can rent camping gear (tent, mat, sleeping bag) at the paid campsites in the park but it’s more expensive than in Puerto Natales. To rent camping gear at Vertice Patagonia campsites will cost you per day; tent (2 people) – CLP 20 000/US$25; sleeping bag – CLP 14 000/US$18; sleeping mat  – CLP 5000/US$6. A good thing about renting at campsites is that you don’t carry camping gear from place to place which makes your backpack significantly lighter. 

Guided O circuit tours start at US$2000 per person it includes accommodation (usually more comfortable option e.g. Eco camps or hotels), transportation, guide, park entrance fee, ferry ticket, luggage transfer, all meals, gear (sleeping bag) if needed. It’s quite a bit more expensive than an independent trek but it’s much more comfortable and easy.

Check here the current conversion.

Where to stay before and after 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.

It looks like 2019/2020 season online booking of CONAF campsites finally works. Though as for November 2019 there are very few open spots available for the months of December – January. If you’re planning to do the circuit in the peaks season I strongly recommend booking free campsites a long time beforehand.

They might keep some spots for booking through the office in Puerto Natales, Manuel Baquedano st. 847. If you’re desperate and can’t find anything available online I’d recommend checking out at the office you might be lucky.

Best time for hiking the Circuit

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.

Items we love taking with on a hike
