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 - 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!
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.
After enjoying lunch and taking photos, we´ll descend to Las Torres Camp, where we’ll collect our backpacks and continue toward the Japanese Campsite. Upon arrival, we will set up camp and rest, preparing for the crossing of Oggioni Pass the following day.

Once we cross the pass, we’ll walk through a dense forest that will lead us to a beautiful view of the Dickson Valley and the camp in the distance. As we descend, we will arrive at our camp.

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.
