Patagonia W Trek in Torres del Paine: Complete 2026 Hiking Guide

Tucked into the far south of Chilean Patagonia, the W Trek in Torres del Paine National Park is one of the most spectacular multi-day hikes on the planet. The trail draws its name from the W shape of the valleys it links, threading between glaciers, ice-blue lakes, granite spires, and the three Torres that give the park its name. For 2026/27 the park has continued to require advance booking through the official Parque Patagonia system, so the trail rewards hikers who plan months ahead rather than weeks.

Why the W Trek and not the full O Circuit?

The full O Circuit circumnavigates the entire Paine Massif in roughly 130 km and usually takes 8–10 days. The W Trek covers about 80 km of the most scenic spine of that circuit in 4–5 days. If your time is short, you are not an experienced multi-day backpacker, or you simply want to see the highlights, the W is the right call. The O is for hikers who want genuine solitude and the wild west arm of the circuit.

When to hike the W Trek

• December – February: Patagonian summer. Long days (sunrise around 5 a.m., sunset after 10 p.m.), warmest temperatures, refugios fully open. This is peak season and the most crowded.
• October – November and March: Shoulder season. Fewer hikers, lower prices, but cold nights and the chance of early snow. The trails are quieter and the light is sharper.
• May – August: Winter. Many refugios and catamaran services close. Heavy snow closes some sections entirely. Not recommended unless you are an experienced winter mountaineer.

For 2026/27, expect the park entrance reservation system to open roughly six months ahead of each day. Treat mid-December through mid-February as booking-critical.

The classic 5-day W Trek itinerary

Day 1 — Refugio Paine Grande to Glacier Grey

A boat from Pudeto catamaran dock across Lago Pehoé drops you at Refugio Paine Grande, from which you walk west along the shores of Lago Grey to a day hike up to Mirador Grey. The reward is a full-face view of the Grey Glacier calving into the lake, with the Southern Patagonian Ice Field behind it. Around 22 km round trip, moderate difficulty.

Day 2 — Paine Grande to Cuernos

The heart of the central valley. You climb past the French Valley junction, with the Cuernos (Horns) of Paine above you on one side and the glacier-clad east face on the other. About 12 km. Finish at either Refugio Los Cuernos or the free Campsite Cuernos if you are camping.

Day 3 — Cuernos to Chileno via the French Valley

The hardest day on the trail if you take the upper detour to Mirador Británico, then about 18–22 km total. From the Británico viewpoint the entire amphitheatre of the French Valley opens in front of you. End the day at Refugio Chileno or the Chileno camp.

Day 4 — Chileno to Torres viewpoint and back

The single most-photographed sunrise in Patagonia. Start in the dark, watch the three Torres catch pink then gold first light, then walk back to Chileno. About 19 km round trip, mostly uphill on the way out.

Day 5 — Chileno to Hotel Las Torres and out

A gentle descent through beech forest back to the park entrance at Hotel Las Torres, where you board your transfer to Puerto Natales. About 8 km.

Refugios, camping, or a mix?

You have three accommodation options on the W:

• Full refugio (mountain hut): Dorm beds and hot meals included. No tent needed. The most comfortable option, the most expensive, and the one that books out fastest.
• Mixed: Refugios some nights, camping on free CONAF sites (Cuernos, Chileno, Grey, Paine Grande) on others. A good balance of comfort and budget.
• Full camping: Bring your own tent, stove, and food. Cheapest and most flexible, but every kilogram matters on the trail.

What to book before you arrive

• Park entry reservation through the official Parque Patagonia portal, released roughly six months ahead.
• Refugio beds if you are not camping — these sell out within hours of release for peak dates.
• Pudeto catamaran ticket if you are doing the standard west-to-east direction.
• Bus or transfer from Puerto Natales to the park entrance, and from Hotel Las Torres back to Puerto Natales at the end.

Gear checklist

• Waterproof shell jacket and trousers (Patagonian weather changes in minutes)
• Layering system for 0–20°C in summer
• Sturdy hiking boots, broken in
• Headlamp, even in summer (long days do not save you in a sudden whiteout)
• Water filter or purification tablets
• High-energy snacks — the standard mountain-hike 3,000–4,000 kcal per day

Sample budget per person (USD, 2026/27)

• Park entrance: roughly USD 35–49 depending on season
• Catamaran ticket: roughly USD 40–55 one way
• Refugio full board: roughly USD 130–180 per night in peak
• Camping + own food: roughly USD 25–35 per night on CONAF sites
• Transfer Puerto Natales round trip: roughly USD 50–70

Expect a 5-day W in peak refugio mode to land somewhere between USD 900 and USD 1,400 per person, excluding flights. Camping drops the floor closer to USD 400–600, again excluding flights.

Final tips

The W Trek is busy for a reason: it is genuinely one of the great walks of the world. The mountain huts are warm, the food is good, and the views are unforgettable. Book early, pack layers, protect your phone from wind-blown grit on the Torres viewpoint, and leave at least one buffer day in Puerto Natales in case the weather closes the trail. Done well, the W is the kind of trip you keep coming back to.
