The 2026 Patagonia W Trek guide: reserve permits, gear checklist, best campsites, weather strategies, and how to combine with Buenos Aires for the ultimate South America trip.
Patagonia — the end of the world, where the Andes meet the steppe in a dramatic collision of ice, wind, and untamed beauty. Torres del Paine National Park’s W Trek is one of the world’s great multi-day hikes: 5 days, 4 nights, through glaciers, turquoise lakes, and granite towers.
Here’s the complete guide for 2026.
W Trek vs O Circuit: Which Route?
W Trek (5 days, ~80km)
- Classic route, most popular
- Passes all major highlights: Base Torres, Grey Glacier, Valle del Francés
- Good infrastructure (campsites, refugios)
- Advance booking essential (especially campsites)
- Best for: First-time Patagonia hikers
O Circuit (8-10 days, ~130km)
- Full loop around Torres del Paine massif
- Includes remote backside with fewer tourists
- Better for experienced hikers seeking solitude
- Requires more gear (longer, more remote)
Permit System 2026
CONAF (Chile’s National Forest Corporation) now requires advance permits for all overnight hikers in Torres del Paine:
How to Book:
- Website: reservas.parqueustral.cl
- Costs: ~$35-45 USD per person per day (campsite + park entry)
- Campsites must be reserved in advance — no first-come basis
- Booking opens: typically September for the following season (Nov-Apr)
⚠️ Critical: The park has a strict capacity limit. Popular campsites (like Torres Central) sell out within hours of opening. Book the day the system opens, or join via a guided group that holds block reservations.

Torres del Paine in Photos
The famous Torres (towers) are best photographed at sunrise when alpenglow turns them pink-orange. Arrive 30 minutes before official sunrise — the view from Mirador Base Torres is crowded by sunrise itself.
Visa & Insurance
Chile: Chinese citizens need a Chile Tourist Visa (apply in advance at consulate).
Argentina: Visa-free for Chinese passport holders with valid US/Canada/UK/EU visas, or apply for Argentine ETA (AVE).
⚠️ Insurance: Remote Patagonia means remote rescue. Medical evacuation from Torres del Paine can cost $20,000-50,000 USD. Comprehensive travel insurance is non-negotiable. Compare options via AirHelp.
