Read on if you dream of an adventure that takes you deep into the wilderness. We will share everything you need to know to conquer John Gardner Pass and come away with a story you will never forget.

What is John Gardner Pass? Where is it located?

Let’s begin with the most important question: What is John Gardner Pass? If you’re reading this, it’s likely your first time in the national park or perhaps your first encounter with the O Circuit. Here are some essential facts to help you travel well-informed.

Like many places in Torres del Paine National Park, such as the Ascencio Valley and Lake Nordenskjöld, John Gardner Pass is named after one of the many individuals who have shaped history in this corner of the world. John Gardner was a member of the British Chilean University Expedition—a joint effort by universities in the United Kingdom and Chile (1957-1958) to survey and map remote areas of Chilean Patagonia, including the Paine Massif, which was still relatively unknown even to Chileans at that time.

John Gardner Pass is located on the west side of the Paine Massif and is the highest point of the O Circuit, reaching an altitude of approximately 1,200 meters above sea level. It connects to Los Perros Camping (to the east) and Paso Camping (to the west). This narrow, high mountain pass offers impressive views of the Grey Glacier, surrounded by steep slopes and exposed to intense winds.

Is it really as difficult as they say?

If you ask anyone who has done the O Circuit, they will probably tell you that the day you cross the John Gardner Pass is the most demanding: a true challenge that, in exchange for the effort, rewards you with one of the most breathtaking views in Chilean Patagonia.

You will face altitude changes of over 600 meters within just a few kilometers, unpredictable weather, and strong wind gusts that can exceed 100 km/h. The pass tests even the most prepared individuals. Having the right gear will be crucial for this adventure, where the ascent is continuous. However, the descent to Grey Camping can prove even more technically challenging and slippery, especially in wet conditions.

The key is to respect the mountain, listen to your body, and start the day very early. Do not underestimate the importance of training ahead of time with long hikes and a loaded backpack. Like a marathon, the O Circuit is a physical challenge requiring advanced preparation.

Gear: Do not leave home without this

We have discussed the importance of training your body for this challenge. Now, let’s talk about what you should bring. This is not a good time to experiment or improvise.  

A good waterproof and windproof jacket is essential, as the weather can change within minutes. As we say in Patagonia: "You can experience all four seasons in one day." It’s important to bring thermal clothing and a change of clothes, as you will sweat on the way up, and then the cold can take its toll. Trekking poles make a significant difference on the descent, which can be steep and muddy. Good gloves, a warm hat, and waterproof shoes with a good grip are crucial allies. Do not forget sun protection, even on cloudy days. Your skin will thank you.  

Remember to bring enough trail rations and water for a demanding day. Of course, dark glasses will ensure nothing keeps you from enjoying the view of this incredible landscape, even when walking into the sun. Do not forget a camera so you can capture the experience in photographs you will cherish forever.

What is the best time for this challenge?

In Torres del Paine, we believe there is no perfect time to visit Torres del Paine National Park; you simply need to be well prepared.  

The best months to cross John Gardner Pass are during the region's summer season, which spans from November to March, aligning with the park's official season. During the other months, the pass remains closed due to inclement weather. January and February typically offer better weather, though they also attract more visitors. In contrast, November and March, the park is quieter. However, it will require more preparation to cope with the changing weather conditions, which increases the challenge of the crossing.

It is important to remember that during the winter months (April to September), the pass is closed to the public for safety reasons, particularly due to the accumulation of snow and the risk of avalanches. It is always essential to consult with park rangers before embarking on the crossing and to check the weather forecast, as conditions in the area can change in minutes. We recommend using AccuWeather for these consultations.

Stories from the top: Hikers who conquered John Gardner Pass

Every person’s experience of completing the O Circuit is unique. It is a personal journey that connects you with nature and your thoughts as you walk. Some have faced unexpected snowstorms, while others have cried upon seeing the Southern Icefields for the first time.

While reviewing anecdotes from individuals who documented their journeys through Torres del Paine National Park, a Brazilian citizen remarked that weather conditions had prevented him from crossing in 2009, but he ultimately managed to cross the John Gardner Pass in 2013 under completely clear skies. He reflected that life had an even more rewarding crossing experience in store for him.

Another foreign visitor in the park noted that one of the most memorable moments of his adventure was crossing the pass through layers of snow that reached up to his knees—a physical challenge he still shares with his friends today. The moment he finally saw the Southern Icefields made all the effort worthwhile.

A Chilean tourist and a group of friends remarked that after crossing John Gardner Pass, no photograph could do it justice. The sensory experience of being in this part of the park is indescribable.

The best scenic spots on John Gardner Pass (Get your camera ready!)

We cannot close this blog without mentioning one of the most essential trip tips: photography! One of the greatest rewards of the John Gardner Pass is its stunning visual beauty, so be sure to have your camera and cell phone ready to capture the most impressive pictures and videos.

From the summit itself, you can enjoy a panoramic view of Grey Glacier, a bluish expanse of ice stretching southward amidst a sea of mountains. As the descent begins, the views continue to amaze. Interlacing forests, lichen-covered rocks, and curtains of low clouds create an almost surreal atmosphere.

The suspension bridges further along the route to Grey Camping are also perfect for photographs: you can admire the glacier in all its grandeur and see the icebergs floating on the lake. If you leave early from Los Perros, you might even be able to capture the golden-tinged forest and snow-capped peaks at sunrise. Without a doubt, this day is a feast for the eyes and for any lens.

Remember that when crossing the suspension bridge, you must keep moving to avoid slowing down other visitors. Hold your cell phone or camera firmly to prevent it from falling.

If you have ever dreamed of standing in front of the Grey Glacier and feeling the power of nature, this is the moment. Get ready, gear up, and cross the John Gardner Pass, a journey that will make you feel you have truly conquered Patagonia.
