If you are the kind of person who loves challenges, the outdoor lifestyle, travel around the world seeking for most wonderful and exclusive places, where it’s just you, nature and the imposing landscape… then, this is what you are waiting for! This program combines navigation and off-trail trekking in the remote and pristine Patagonian fjords, completing a unique lifetime experience.

This trekking circuit begins in the Resi fjord, and crosses to the Mountains’ fjord through a pass created by the strong erosion of a gone glacier. We go through a beautiful valley that is characterized by evergreen forests, waterfalls, peatland, rocks and moraines just colonized by lichens and mosses. We trek by imposing mountains with whimsical shapes until we arrive to the “thunder” lagoon, where we begin a steep uphill on a rock wall till the pass. When we get to cross to the other side, it will be possible to admire the magnitude of the Mountains’ fjord and the majestic Sarmiento mountain range with its summits covered by centenary ice that feeds many hanging glaciers and five main glaciers that flow down to the fjord. We'll have a hallucinative panoramic view of the fjord that seems tiny surrounded by huge mountains and glaciers that rise in the horizon.

We'll spend the first two nights in our mobile campsites, where we’ll have a dome as shelter and dinning room at the end of a nice trekking day. On the third day we’ll arrive to enjoy of our exclusive floating refuge “Explorador”, where we’ll take our fast boat to navigate until the Bernal glacier, that gives us the chance to watch all its beauty while we hike along its colorful moraines that cross its pro-glacier lake, being possible to get to touch its ice. Our professional local guide will give us a speeches in terrain, so we can know better about the landscape, its formation and the powerful ancestral cultural history of the area.

Finally we go back to Puerto Natales hiking through a beautiful path known as “Alacalufe”, same name that was given to the canoeist ancestors who inhabited all the fjord lands in the last 5,000 years, and used this pass to connect the Mountains’ fjords with the Resi fjord, where we began our trekking circuit. From here we go back the same way we did the way in. We embark to a fast boat to navigate one and a half hour until the Antonio Varas peninsula. Afterward we continue 45 minutes by car on a gravel road until the ferry that will take us across the Señoret channel to Puerto Natales.


We begin by taking a ferry to go across the Señoret channel to the Antonio Varas peninsula, located in front of Puerto Natales. Then we continue by car for 45 minutes through a gravel road , to the embarking spot, where we’ll have lunch. Afterward we take a fast boat and navigate one and a half hour until the end of the Resi fjord. Here we have our first mobile campsite with a dome as shelter along with a dinning room.
On the way we might see seals, dolphins, penguins, cormorants, condors, and other species.

If the weather conditions were favorable and lets us arrive early, we’ll hike in the surrounding to watch and appreciate the beauty of the area. We finish the day with a tasty dinner in our dome.


After breakfast we begin our trekking circuit. We go 8 kilometers through a beautiful valley characterized by evergreen forests, waterfalls, peatland, rocks and moraines colonized by lichens and mosses. We trek for about 4 hours by imposing mountains with whimsical shapes until we arrive to the “thunder” lagoon, which is surrounded by huge rock walls that looks like an amphitheater. The powerful action of a gone glacier has transformed one of these rock walls into a natural pass that makes it possible to trek uphill through terraces till the Mountains’ fjord. We will enjoy our boxed lunch at the pass.

From the pass it's possible to see some of the summits cover by centenary ice which belong to the Sarmiento mountain range. We continue through moraines and erotic blocks passing by two beautiful lagoons until we finally have a clear view of the entire fjord that appears tiny surrounded by huge mountains and glaciers in the horizon. From here, the terrain towards our second campsite in front of the Kiara glacier is more rocky and solid, making it an easier hike. Here, we have a dome for shelter and dinning room to enjoy another nice dinner with an exclusive panoramic view.


We begin the day with a good breakfast. Then we’ll navigate 10 minutes from the campsite towards the North, to a beautiful beach with a glacier in the background. Here begins our trekking; we’ll gain one thousand feet of elevations until we get to a panoramic lookout of the glaciers Alsina and Paredes, that fall down from the icy summits of the Sarmiento mountain range till the fjord itself.
We come back down to the beach the same way we went up, but this time we’ll trek 7,5 miles towards the South. Half way we’ll pass by where our last campsite was. The terrain is similar to what we have seen already; rivers, erratic rocks and curious birds that will follow us as we go. Somewhere on the way we’ll stop to eat our boxed lunch.

We will arrive to a bay in front of the Hermann glacier, where the boat awaits for us to take us across the fjord, 10 minutes until the Bernal glacier. We disembark in the coast and then hike through a particular trail with colorful moraines that cross the pro-glacier lake, allowing us to get close and safe enough to touch its ice. This permits us to watch and understand its movements and changes it makes in the landscape through the years, complemented with a pleasant speech given by our professional local guide. The contrast of colors between the vegetation, the ice, the mountains and the fjord in the background, makes any picture postcard worthy.
After visiting this glacier, we navigate again in our fast boat another 15 minutes to the remote Huiros bay, where we will find our exclusive floating refuge “Explorador”, where we’ll enjoy facilities, a hot shower and a delicious parting dinner.


After a nice breakfast, we’ll head back to Puerto Natales, hiking through the “Alacalufe” path, named as the canoeist ancestors who inhabited all the fjord lands in the last 5,000 years,. They used this pass to connect the Mountains’ fjord with the Resi fjord. After one and a half hour of hiking, we’ll reach the Acantilados lake, which is incased between huge rock walls; it’s only possible to go across by boat, taking five minutes. Once at the other side, we walk for another 30 minutes to arrive to the Resi fjord.

Here we take our fast boat to navigate one and a half hour until the Antonio Varas peninsula as day one. We eat our lunch and continue until Puerto Natales, finishing this trip around 16:00.

As it's explained in the itinerary, to complete this great expedition, we must combine land transportation (white line), maritime transportation (orange line) and trekking (green line).
