Some trips start with a plan. This one started with a flight to Santiago, a connecting flight to Puerto Natales, and absolutely no idea how much I’d fall in love with a piece of trail in southern Chile.
Getting There
The journey itself is part of the adventure. Santiago is just the gateway — from there, a short flight south drops you into Puerto Natales, a small, windswept town on the edge of Última Esperanza Sound. It’s the kind of place that feels like the edge of the world, in the best way.
Puerto Natales: More Than a Pit Stop
Most people treat Puerto Natales as a one-night layover before the trek. Don’t make that mistake. I spent time wandering the waterfront, ducking into cozy cafés for empanadas and pisco sours, and swapping stories with fellow travelers gearing up for the same trail. Hostels here have a way of turning strangers into trail family fast — by the time I caught the bus to the park, I already had a crew.
The Trail Begins
From Puerto Natales, it’s a bus ride followed by a shuttle to the trailhead — and then the W Circuit unfolds over four unforgettable days. Towering granite spires, glacier-fed lakes in impossible shades of blue, and wind that genuinely tries to knock you sideways (Patagonia doesn’t do “gentle breeze”). Each day brought a new landscape, and by the end, a payoff that made every blister worth it.
The Real Magic: The People
Here’s the thing nobody tells you about the W Circuit — the trail is incredible, but the people make it unforgettable. Refugios (the trail huts) turn into nightly gathering spots where hikers from a dozen countries trade trail snacks, blister remedies, and travel stories over simple dinners. I started the trek with a couple of friends and finished it with an entire international crew I still keep in touch with today.
Day-by-Day Itinerary
Day 1 — Mirador Base Torres | ~9 hours
This one tested us right out of the gate. Our bus ran late, pushing our start back and turning an already long day into a 9-hour one. The elevation gain caught a lot of people off guard — it climbs fast, and you feel every bit of it. The last 1 to 1.5 miles were the toughest part of the entire day — a steep, relentless scramble over big boulders that demanded full attention with every step. And in true hiking-trail fashion, every single person we passed coming down and asked “how much further?” gave us the same answer: “about 45 minutes.” We heard that “45 minutes” for what felt like two hours straight — it became a running joke by the time we finally reached the top. Just as we were closing in on the refugio, the skies opened up and we finished the day completely drenched. But that’s the beauty of the trail system here — a hot shower and a hot meal waiting at the refugio turned a brutal day into one of my favorite memories. Nothing tastes better than dinner after a day like that
Tip: Pack a proper rain shell, not just water-resistant gear. Patagonia weather doesn’t negotiate.
Day 2 — Francés Sector
Everyone told us this would be the “easy day.” It was not. Rolling hills made it more deceptive than expected, but the real challenge was the wind — and I mean genuinely wild, knock-you-sideways wind. At one point I got physically pushed into the bushes off the trail. Patagonia doesn’t do gentle breezes; it does full-force gusts that demand respect.
Day 3 — French Valley
We set out for the French Valley but got hit by a snowstorm partway through, which sent everyone back to the refugio earlier than planned. What could’ve felt like a disappointing, cut-short day turned into one of the best nights of the trip — half the trail ended up stuck at the same refugio, and we spent the evening swapping stories, sharing food, and making friends we’re still in touch with. Sometimes the trail’s best moments happen when the plan falls apart.
Day 4 — Grey Glacier
A long-awaited highlight. We hiked to Point 1 and got our first real look at the glacier — massive, blue-white, and otherworldly. We had to skip Point 2 since we had a 5pm ferry to catch, but even Point 1 delivered. A solid reminder that on the W Circuit, the schedule sometimes makes the call for you.
Why You Should Go
If you want a hike that’s equal parts physical challenge and social adventure, the W Circuit delivers both. Go for the views. Stay for the friendships you didn’t expect to make.
For me, this trip was something more — it was my introduction to multi-day backpacking. There were moments on the trail where I genuinely questioned what I had gotten myself into, where my legs were done and the “45 minutes” kept coming and the rain wouldn’t stop. But somewhere between the snowstorm on Day 3 and the glacier on Day 4, something shifted. I finished the W Circuit already planning the next one. And that might be the best thing a trail can do to you.
