If Patagonia is not one your trekking bucket list, you may have missed the pictures of turquoise lakes, snow-powdered peaks, and the most dramatic glaciers. Indeed, when talking about trekking in Patagonia, we are not referring to a famous clothing brand. Patagonia is an area the size of almost 1 million (!) square kilometers shared by Argentina and Chile. It’s massive so where do you start? Your trekking in Patagonia starts right here.

Argentina and Chile share the pie that is Patagonia. There is a healthy competition between the two South American countries about which side of Patagonia is best. Although there literally are dozens of National Parks scattered over Chilean and Argentinean Patagonia, there are two National Parks that grab all the attention from trekking enthusiasts. Torres del Paine National Park on the Chilean side and Los Glaciares National Park on the Argentinean side. 

As beautiful as the pictures you see look, Patagonia is a treacherous place that should be treated by respect. Names like the O-Circuit or the W-Trek may sound like you are about to take a walk through the park, but the weather conditions in Patagonia can be hard to gauge and especially treks to El Chaltén and the O-Circuit asks for thorough preparation. Let’s break the options down for you so you can make a well-informed choice when you are heading off for your Patagonia trekking.

Trekking in Chilean Patagonia - Torres del Paine

There are dozens of options but many end up at Torres del Paine. It not so hard to understand why. Torres del Paine National Park is home to Las Torres, the Towers. When thinking of Patagonia trekking and trying to find information about it, you are likely to find a photo of the Towers. It makes for a great wallpaper!

There is however more in Torres del Paine. The Grey Glacier, the hanging glacier in the French Valley and the famous Grey Glacier. In Torres del Paine, you are lucky to have all these beautiful highlights within trekking distance. The W-Trek strings all of them together and it is safe to say that this is the most popular trekking option in the entire of Patagonia. The O-Trek, which takes typically twice as long, is also a popular option and includes the Southern Ice Field.

W-Trek Overview

The W-Trek is by far the most famous trek in Patagonia. The W stands for the shape of the route if you look at it from a bird’s eye perspective. There are many options if you want to conquer this massif. Although the W-trek is the shortest, it includes the most beautiful highlights of the park.

The W-trek is not that long, which is why many mountaineers choose to do it in 3 days. Nevertheless, we recommend taking it a little bit slower so as to make the most out of every site. With the most varied and colorful landscapes, this trek is guaranteed to leave you speechless. Along the way, you will find hanging glaciers, waterfalls, rivers, lakes, and granite peaks. The red color given by the lengas in autumn and winter provide you with dreamlike sceneries.

5-day W-Trek Itinerary

  • Day 1: Transfer to Torres del Paine – Round trip hike to Las Torres lookout point
  • Day 2: One way hike to Los Cuernos lookout point
  • Day 3: One-way hike to Pehoe Lake, via the French Valley
  • Day 4: One-way hike to Glacier Grey – Optional Ice hike or kayak
  • Day 5: One-way hike to Catamaran – Transfer back to Puerto Natales

A typical W-Trek itinerary starts and ends at Puerto Natales. Accommodation is typically included when you book a guided or self-guided trek, but this very much depends on availability at the local refugios. Keep reading if you want to know what you can expect at these refugios.

O-Circuit Trek Overview

The O-Trek or the Circuit Trek is a Patagonian classic. The popular hiking trail in Torres del Paine National Park lures the intrepid travelers of this world to South America. It is for those who want to do more than just the W-Trek and know that they have the right physical abilities. As the name suggests, the O-Trek, better known as the O-Circuit, is a circuit. The “O” includes the “W” but things are a bit more interesting because the backside of the mountain gets added in the shape of a long leep.

All in all the O-Trek is worth more than 100 kilometers. You can do the O-Trek in different variations, but most people try to tackle it in about 7 nights and 8 days. There is a limit on the O-Trek, as only 80 people are allowed on the backside of the mountain each day. Will you be one of them? Think turquoise blue lakes, the famous towers of the Torres del Paine, stunning vistas, and a little bit more.

Trekking in Argentinean Patagonia - Los Glaciares

Los Glaciares. It is as majestic as the Spanish name sounds. You’ve guessed it, Los Glaciares means The Glaciers and there are plenty of glaciers to be found in this National Park. In fact, Los Glacieres counts 356 glaciers. You could almost see a glacier a day for an entire year. Obviously, it doesn’t work like that, you can’t just get off the trails and you really don’t have to. From conquering the summit of Mount Fitz Roy to walking over the Perito Moreno Glacier, this park is what every trekker ever dreamed of.

Los Glaciares National Park was declared a World Heritage Site by the UNESCO in 1981 because of its natural beauty, its breathtaking landscapes, and its unique flora en Fauna. While trekking in the park you can get deep in Lenga Forests, camp under the starry night, and walk over, you’ve guessed it again, glaciers.

Los Glaciares National Park is mostly about El Chaltén, Fitz Roy and the Southern Patagonian Icefield. The last one can be accessed via the O-Trek in Torres del Paine as well, but it is just so much easier in Los Glaciares. Of course, there is also Perito Moreno Glacier, but as this can be done in just a day trip, we leave it out the perspective. Let’s give you the break down for some proper Patagonia trekking in Los Glaciares:

How To Get Fit for Trekking in Patagonia

One sure way to get good at what you do is to practice. The best practice for hiking is hiking. Seeing that you are interested in trekking Patagonia, we assume that you already like hiking to some extent. Hike a bit more. If you are lucky enough to be surrounded by hills or even mountains, it is time to see them more often. When? If you are new to this, we suggest starting six months before your planned departure by simply going for an hour (or two) hike a week. When you get the hang of it, after about three weeks, it’s time to beef up your intensity. Bring a pack of 10 to 15kg and add a longer hike of three hours to your week. If this lifestyle is new to you, you will soon reap the benefits of trekking.

After a good few months of solid hiking, it is time to put your endurance to the test. Do back-to-back long hikes. You can simulate a few days of constant trekking by going hiking for a few days. Easy at that. Plan a smaller trekking holiday or keep it simple by hiking your favorite route on repeat. If you are comfortable hiking for 4 hours a day, 3 days in a row while carrying a 10kg to 15kg backpack, you will be fine.
