Hiking in Torres del Paine

About the National Park Torres del Paine

The »Turismo Lago Grey National Park« was founded in 1959. Just two years later the park was renamed as »Torres del Paine National Park«.

The Torres del Paine National Park (Parque Nacional Torres del Paine) is the most famous national park in Chile, surrounding the mountain range Cordillera del Paine in the south of Chile. The Aónikenk people, better known as the Tehuelche, were a group of indigenous peoples living in this area long before the Europeans discovered this region of the world. The word Paine means “Blue sky” in native Tehuelche language and is pronounced PIE-nay. The most important monument of the National Park Torres del Paine (“Blue mountains”) is the Los 3 Cuernos. The three granite mountains in the middle of the parc.

The park possesses a massive network of rivers, streams, and lakes all fed by the Southern Patagonian Ice Fields – the second most massive extrapolar contiguous Ice Field in the world. The largest is the Glacier Grey which can be visited by Kayak during the completion of the O Trek at Refugio Grey (add a half-day to your itinerary).
A great benefit, next to the stunning views over the glacier, is that you don’t have to carry water with you. There is plenty everywhere you go.
Occasionally, the park is associated with its unofficial title »Eighth Wonder of the World« and has been elected as the fifth most beautiful place in the world by National Geographic.

Both the W and the O Trek are entry level hiking treks. They offer an excellent opportunity to fall in love with the great outdoors.

How to get to Torres del Paine

Step one: International flight to South America

The easiest way to get to the Torres del Paine National Park is from Chiles capital Santiago de Chile. You can also reach it from Argentina, but this will take longer.

Step two: From Santiago de Chile to Punta Arenas

For more detailed information read our article “How to get to Patagonia.”

Step three: Bus from Punta Arenas to Puerta Natales

It is possible to take a bus directly from the Punta Arenas Pres Ibanez airport to Puerto Natales as well as to the Torres del Paine National Park. Check timetables ahead to avoid extra stops!

Alternatively, take a taxi from the airport to the city center, where the bus station is located; this will cost around 10.000 CLP. At the bus station, you can book a bus towards Puerto Natales.

There is a huge supermarket (UNI Marc) in the city center, where you can buy most of the food you will need for the trek. In case you didn’t make reservations for the refugios (camps) on the trek, you have the chance to visit and ask for a last minute reservation at one at the sales offices.

What is the best time to hike the O Trek 

For more detailed information read our article “Weather in Patagonia

The best time to trek in Patagonia is during summer. The season starts in December and ends during March. Due to the geographic length of the country (1500km), there is a high-temperature difference from north to south.

However, it always depends on what you are looking for. Spring can be fantastic in the lower altitudes, but you might need crampons or snowshoes in higher elevations.

The weather, in general, is volatile; be equipped for every situation.

Why should I hike the O Trek during the summer?

In Patagonia, it is normal that the wind speeds reach up to 100 km/h during a normal day. Keep this in mind while crossing a mountain ridge or while walking over a field of loose stones.
A wind protected campsite is a pleasure after a long and tiring day on the trek.

During summer time you will have nearly 22 hours of daylight. (Diagram)

How to book campsites on the O Trek

The campsites on the O Trek are owned by two companies as well as the government. Each campground has to be reserved separately, and the operation of the individual websites can get frustrating due to page issues and loading speed which makes the planning of the trek quite challenging.

    I have never seen anything like those 3D Maps. Very cool! How do you make them?

    Cheers, Derek.

      Hey Derek!

      Thank you so much! We use Photoshop and a plugin called “3D Map Generator – Atlas”. It is a lot of work, especially the texturing takes a lot of time. We love them too though! 🙂

      All the best,
