Choosing Your Path in Torres del Paine: The W Trek vs The O Circuit

If you’re planning a trekking adventure in Torres del Paine, one of the first decisions you’ll face is choosing between the W Trek vs O Circuit, the park’s two most iconic routes. Both offer unforgettable experiences—but each caters to a different type of traveler.

Let’s explore the main differences in this comparison of W Trek vs O Circuit in Torres del Paine, so you can decide which route best matches your goals.

Understanding the Park’s Geography

Torres del Paine National Park spans over 180,000 hectares (445,000 acres) in southern Chilean Patagonia, just 112 km north of Puerto Natales. It’s home to legendary landmarks like the granite Towers (Torres del Paine), Los Cuernos, Glacier Grey, and the John Gardner Pass.

The W Trek runs through the southern section of the park, forming a “W” shape across three valleys. The O Circuit loops around the entire park, including the W Trek and more isolated northern trails.

Duration & Difficulty

The W Trek is about 80 km (50 mi) long and takes 4 to 5 days to complete. It’s ideal for moderately fit hikers, thanks to accessible refuges and shorter daily hikes (5–8 hours).

The O Circuit spans approximately 110 km (68 mi) and requires 7 to 9 days. It involves longer trekking hours (6–10 hours per day) and includes the challenging ascent to John Gardner Pass (1,200 m / 3,900 ft), making it perfect for those craving a deeper wilderness experience.

Accommodation Differences

On the W Trek, you’ll find cozy refuges and designated campsites, both offering meals and hot showers. It’s even possible to hike the W without carrying all your gear, thanks to full-service trekking programs.

In the O Circuit, camping is mandatory in the northern section—there are no refuges between Las Torres and Dickson. For this reason, booking in advance and having proper camping gear is essential.

When to Go

The official trekking season runs from October to April, with peak months between December and February. The W Trek is accessible year-round, including in winter (guided only). The O Circuit is only open during summer months—usually mid-October to March.

Prepare for unpredictable weather in both routes. Wind, rain, and sudden drops in temperature are common, so pack smart with layers and waterproof gear.

W Trek vs O Circuit – Which Trek Is Right for You?

Choose the W Trek if you:

• Have limited time (4–7 days)
• Prefer more comfort and flexibility
• Want easier access to services
• Are visiting during shoulder season or winter (W Trek is available year-round)

Choose the O Circuit if you:

• Have 8–10 days available
• Are physically prepared for longer daily hikes (6–10 hours)
• Want to experience the impressive John Gardner Pass and Northern Sector
• Enjoy immersive multi-day trekking

Pro Tips Before You Go

• Book all accommodations early—refuges and campsites fill up fast
• Rent your gear in Puerto Natales; there are no rentals inside the park
• Bring a 35–40L backpack and layer your clothing for variable conditions
• Consider a guided tour for safety and local insights
