Epic adventure in Torres del Paine
A demanding trek for true adventurers. This circuit requires good physical condition and a spirit of exploration, as it leads through remote sections of Torres del Paine National Park, crosses a dramatic mountain pass, and reveals some of Patagonia’s wildest and least-traveled landscapes.
Day 1 - Round-trip hike to the Base of the Towers
We’ll depart from Puerto Natales at 6:30 AM heading toward Torres del Paine National Park. Along the way, we’ll pass by estancias and open pampas. Get ready to be amazed by the stunning landscapes, flora, and fauna of Patagonia. Don’t forget your camera! Upon arrival at the refugio, you’ll be able to leave your luggage before starting the hike to the Base of the Towers.
We’ll begin the hike by entering the Ascencio Valley, gradually ascending until we reach the Windy Pass. This section is as breathtaking as it is exposed, with strong wind gusts, so it’s essential to follow your guide’s instructions to cross safely.
Just a few minutes ahead, we’ll arrive at Refugio Chileno, the last point on the trail with bathrooms, food for purchase, and internet access. Be sure to bring cash if you plan to buy anything.
From there, we’ll continue into a lenga forest, crossing small streams until we reach a scenic viewpoint that reveals the next, and most challenging, stretch of the day. The trail then climbs steeply over a massive terminal moraine, where we’ll be rewarded with the awe-inspiring view of the iconic Towers.

We will ascend to John Garner Pass, reaching 1,200 meters (3,937 feet) above sea level, where you’ll feel the strong Patagonian winds and be dazzled by the Grey Glacier and the still-unexplored peaks of the Southern Patagonian Ice Field.

Our traveler’s experiences

Excellent guides, unforgettable memories
The hike was challenging but totally worth it. The scenery was outstanding and the reason we decided to visit Patagonia. The guides, Pablo and Fran, were simply amazing and made the whole experience so memorable. I’ve done several hiking trips, and this was the first one where I used a guide service. I’m so glad I did.

A transformative adventure
Excellent! It met our expectations and much more. Our guides, Mauricio and Fernando, were very friendly, always putting safety first, and were very knowledgeable about the area. They answered all our questions enthusiastically, were great cooks, and kept us informed about what was coming next. Excellent guides, and I would highly recommend them.

A balance of learning and adventure
I can’t say enough about Mauricio, Gerardo (our guides), and the organization of Chile Nativo. We had a wonderful trip, everything felt extremely well organized, and I always felt safe and well taken care of. Our guides made the trip feel special and managed our group, which had a wide range of personalities, very well. They also did a great job explaining the park and our hike, helping us learn about Patagonia.

Exceptional guides, unforgettable experiences
Amazing! We went on our honeymoon and couldn’t have asked for more. The guides were excellent, especially Fernando. His knowledge, friendly nature, and patience were outstanding.

Every minute, a unique experience.
Excellent hike, I enjoyed every minute. There were many companies doing the same trip, but I’m so glad I chose this one! Everything was smooth when making the reservation, the itinerary details were clear, and I felt well taken care of.
