The W Trek is iconic. The O Circuit is life-changing. The Patagonian wind will absolutely humble you on either. This guide breaks down the two big Torres del Paine treks for 2026 — what they actually cost, which one suits which traveler, when to go, and the gear and booking quirks nobody mentions until you're standing in the wind without them.
W Trek vs O Circuit: Which Is For You?
| Feature | W Trek | O Circuit |
|---|---|---|
| Length | ~80 km | ~130 km |
| Days | 4–5 | 7–9 |
| Difficulty | Moderate | Moderate-hard |
| Crowds | Busy | Quiet (numbers capped) |
| Best for | First-time trekkers, tight schedules | Experienced hikers wanting solitude |
| Booking window opens | ~July prior year | ~June prior year |
Short version: if you have 5 days and want the highlights (Grey Glacier, French Valley, the Torres), do the W. If you have 9 days, are fit, and want the back side of the park almost to yourself — including the gut-punch beauty of the John Gardner Pass — do the O.

Two booking platforms run almost all park accommodation: Vertice Patagonia (west side) and Las Torres Patagonia (east side). Both release space starting in June/July of the prior year. By October, the best dates are gone. Book accommodation before flights.
When to Go
- December – February: Warmest, longest days, most crowded, hardest to book.
- November & March: The sweet spot. Fewer people, still mostly open, slightly lower fees.
- April: Quiet and golden, but unpredictable; some refugios start closing.
- May – October: Off season. O Circuit fully closed. Only experienced winter trekkers should attempt the W with a guide.
The Gear Nobody Warns You About
- Wind, not cold, is the enemy. 100+ km/h gusts are routine. A truly windproof shell beats an insulated jacket.
- Trekking poles aren't optional. The descents off the Torres and the John Gardner Pass shred knees without them.
- Buff/balaclava. Sandstorms off the lakes are a real thing.
- A power bank. Refugio outlets are rationed. Bring at least 10,000 mAh.
- Cash in Chilean pesos. Card readers fail constantly inside the park.
- Real boots. Trail runners are common but the scree on the Torres ascent punishes them.
Sample W Trek Schedule (5 Days)
Day 1: Bus + ferry to Paine Grande. Hike to Refugio Grey (~11 km). Glacier view from the suspension bridges.
Day 2: Grey back to Paine Grande, continue to Refugio Frances (~22 km — the hardest day).
Day 3: French Valley out-and-back (~12 km). Sleep at Cuernos or Frances.
Day 4: Hike to Refugio Chileno (~14 km). Early dinner, early bed.
Day 5: 4am headlamp climb to Mirador Las Torres for sunrise. Descend, bus back to Puerto Natales.
What Nobody Warns You About
- Refugio food is hot, plentiful, and shockingly good — but $25–$35/meal. Bring snacks anyway.
- Weather changes every 90 minutes. Pack for all four seasons every single day.
- The 4am Torres climb is dark, cold, and steep. Most people underestimate it. It's still worth it.
- The wind sound at night through the refugios is genuinely unsettling at first.
- El Calafate (Argentina, 4-hour bus) makes a perfect rest stop and adds Perito Moreno glacier for two more nights.
Key Takeaways
- W Trek = 4–5 days, classic highlights. O Circuit = 7–9 days, real solitude.
- Book refugios in June/July of the year before — they sell out by fall.
- November and March are the smartest months to go.
- Budget $1,800–$3,200 all in from the US/UK depending on route and stay mix.
- Windproof shell, poles, cash and a power bank are non-negotiable.
FAQ
Q: Can I do the W Trek without a guide?
A: Yes — it's well-marked and busy. Solo trekkers with basic experience do it routinely. The O Circuit is also self-guidable but requires more planning.
Q: How fit do I need to be?
A: For the W: comfortable walking 6–8 hours a day with a 8–10 kg pack. For the O: same but for 9 days with a 4,000+ ft pass on Day 6.
Q: Should I add El Calafate?
A: If you have the days, yes. Perito Moreno glacier is unforgettable and the bus connection is straightforward.
Final Thoughts
Patagonia is the rare trip that lives up to every photo. Book your refugios this summer for next season, train with a loaded pack for two months beforehand, and pack like the wind will personally try to take your jacket — because it will.
