Hiking Laguna de Los Tres in Patagonia Was the Ultimate Bucket List Adventure

The 15-mile trek to Mt. Fitz Roy and Laguna de Los Tres from El Chaltén was an experience I'll never forget.

The hike to Laguna de Los Tres is one of the most popular adventures in Patagonia, and for good reason. It features some of the most beautiful landscapes in the world: glowing turquoise lakes framed by 11,000-foot peaks. What we experienced was unforgettable solitude and freedom; a place where you can walk for miles without encountering another human.

It was a clear summer day, and we only saw a handful of other hikers on the trail the entire time. Extreme crowding and trashed trails? Hiking elbow to elbow with strangers? Battling for parking spots at trailheads? Not here.

We came all this way to have the adventure of a lifetime. And that's exactly what we got.

Setting Out from El Chaltén

The town of El Chaltén, often dubbed Argentina’s trekking capital, feels like the edge of the world and in many ways it is. Nestled in Los Glaciares National Park, it’s a haven for hikers, climbers, and anyone hungry for an encounter with wild beauty. But nothing quite prepares you for the feeling of stepping onto the trail toward Laguna de Los Tres.

We started early, the kind of early where the morning light is just brushing the peaks with a faint pink glow. The air was crisp, filled with the scent of wildflowers and that indefinable freshness you only get in remote places. The first few miles lulled us into a false sense of ease; gentle inclines, broad valleys, and a breeze that felt like it carried whispers from the mountains themselves.

The In-Between: Miles and Meaning

The trail wove its way through lenga forests and across open meadows dotted with firebrush and tiny magellan daisies. We walked in a rhythm that felt almost meditative, the sound of our boots mingling with birdsong. A flash of movement in the distance revealed a guanaco grazing among the bushes, unfazed by our presence. Overhead, a caracara wheeled lazily, and every now and then we’d stop to listen for the tap-tap-tap of a woodpecker or catch a glimpse of a hare darting across the trail.

We passed through Campamento Poincenot, where early risers were emerging from tents, their breath visible in the cold morning air. We weren’t staying overnight, but there was something sacred about the hush that lingered in those campsites, like everyone there understood they were somewhere special. We paused for a snack beneath a gnarled tree, its branches shaped by years of wind, its roots gripping the rocky soil like fingers refusing to let go.

With each mile, I felt like I was learning something new about her, my fiancé, my adventure partner, the woman who had said yes just days before when I asked her to marry me above the thunderous spray of Iguazú Falls. This hike wasn’t on her bucket list. She agreed to it because she trusted me, because I asked, because love sometimes looks like stepping outside your comfort zone in muddy hiking boots. And somewhere between mile four and five, I realized that every step forward wasn’t just about reaching a glacial lagoon. It was about walking into our next chapter together.

The Climb Begins

After crossing the Rio Blanco, the trail made it clear: the warm-up was over. The final ascent to Laguna de Los Tres is notorious, a steep, switchback-filled climb that demands everything your legs and lungs can offer. It was the kind of climb where you question your life choices, bargaining with yourself, "Just 10 more steps, then I can rest."

But here’s the thing about pushing your limits in a place like this, the scenery conspires to distract you. Behind us, the valley stretched out like a painted canvas, hues shifting with every step higher. Above, Fitz Roy stood stoic, its jagged peaks slicing the sky, daring us to reach closer.

Reaching the lagoon

And then, just when you think you can’t take another step, you crest the final ridge... and there it is. Laguna de Los Tres. A liquid sapphire cradled by glaciers, reflecting the towering spires of Mt. Fitz Roy like a sacred mirror.

We dropped our packs, too awestruck to speak. The exhaustion melted away, replaced by an overwhelming sense of wonder. Sitting there, boots off, toes dipped in the icy water, ice cold beer cracked open, it felt like we’d stumbled into a dream stitched together by nature’s most brilliant artist.

Solitude in the Silence

Despite its popularity, we had long stretches where it felt like the world belonged to us alone. The silence was profound, broken only by the occasional call of a condor overhead or the soft crunch of gravel underfoot. There’s a kind of clarity that comes with that silence, an unfiltered connection to the landscape, and maybe even to yourself.

I thought about the miles we’d walked, the sweat and the struggle. The paradox of adventure is that it’s both about the place and the journey. Sure, the views are breathtaking, but it’s also about the conversations had between switchbacks, the quiet moments of reflection, the small triumphs with every step forward.

The Descent: Reflections and Reverence

Coming down, gravity was both friend and foe. Knees protested, but spirits soared. The landscape felt different on the return, bathed in the golden hues of late afternoon. We passed the same twisted trees, crossed the same rivers, but it was as if we saw them anew, changed by the experience.

Back in El Chaltén, nursing sore muscles and recounting the day over a hearty Patagonian meal, it hit me... this wasn’t just a hike. It was a pilgrimage. A reminder of what it means to feel small in the best possible way, to stand humbled by nature’s grandeur.

Why This Adventure Stays With You

Laguna de Los Tres isn’t just a destination; it’s a testament to endurance, to the power of wild places, and to the transformative magic of putting one foot in front of the other. It’s the kind of adventure that etches itself into your memory, not just for the vistas, but for how it made you feel alive, present, and wildly, unapologetically free.

If you ever find yourself longing for an adventure that challenges and rewards in equal measure, where the path is as breathtaking as the summit, put this trek at the top of your bucket list. Because some places don’t just take your breath away; they give you something far greater in return.
