Trekking in Patagonia: The W Trek and the Highlights of Chile’s Iconic Trail

Few places stir the soul like Patagonia—a land where jagged peaks, turquoise lakes, and vast glaciers converge at the end of the world. For hikers, this remote region on the southern tip of South America is a dream come true, and at its heart lies one of the most breathtaking multi-day treks on the planet: the W Trek in Torres del Paine National Park, Chile.

If you’re craving adventure, solitude, and unforgettable scenery, trekking in Patagonia is one of the most rewarding journeys you can undertake. At The Adventure People, we offer carefully curated Patagonia tours that take care of the logistics—so you can focus on the experience.

What Is the W Trek?

The W Trek is a 4 to 5-day hiking route through Torres del Paine National Park in southern Chile. Named for its distinctive “W” shape on the map, the trail covers around 75 kilometres and takes you into three of the park’s most iconic valleys: Valle Ascencio, Valle Francés, and Glaciar Grey.

Unlike longer and more remote expeditions, the W Trek is accessible, manageable for fit travellers, and can be done independently or on a guided tour. Along the way, you'll stay in refugios (mountain lodges) or pre-set campsites, enjoying a hot meal and a bed at the end of each day.

Where Is It?

The W Trek is located within Torres del Paine National Park, part of Chilean Patagonia. The closest hub is Puerto Natales, a small town that serves as the gateway to the park. You’ll usually fly into Punta Arenas (or sometimes El Calafate if combining with Argentina’s Los Glaciares National Park) and take a bus or transfer north.

W Trek Overview: The Classic Itinerary

Here’s a day-by-day overview of what the W Trek looks like:

Day 1: Base of the Torres

• Distance: 18km return

• Hike to the iconic granite towers that give the park its name: the Torres del Paine.

• It’s a long but rewarding day with steep ascents and epic views of the spires reflected in a glacial lagoon.

• Highlight: Watching the sun rise or set behind the towers if you stay in nearby Refugio Chileno or Refugio Torre Central.

Day 2: Hike to Los Cuernos or Francés Valley

• Distance: 11–13km

• A more moderate day along the shores of Nordenskjöld Lake, with stunning mountain and glacier views.

• Overnight at Refugio Los Cuernos or Domos Francés, where the scenery begins to feel truly wild.

Day 3: The French Valley (Valle Francés)

• Distance: 17–20km

• A spectacular day hike up the middle leg of the “W,” through the lush, glacial-carved French Valley.

• Stop at Mirador Británico for panoramic views of jagged peaks in all directions.

• Return to camp at Paine Grande, located on the edge of Lake Pehoé.

Day 4: Glacier Grey

• Distance: 22km return or shorter depending on ferry options

• Trek along the western arm of the W to the jaw-dropping Grey Glacier, one of the park’s most famous sights.

• Icebergs float in the lake below as the vast glacier tumbles down from the Southern Patagonian Ice Field.

• Optional boat ride or kayaking excursion near the glacier.

• Overnight at Refugio Grey or return to Paine Grande and ferry out.

Day 5 (Optional): Return via Lake Pehoé Ferry

• Catch the catamaran from Paine Grande across Lake Pehoé to meet your transfer back to Puerto Natales.

Trip Highlights: Why Trek the W?

🏔 Iconic Scenery

The W Trek packs in the most iconic views of Torres del Paine:

• The three granite towers (Torres)

• The hanging glaciers of French Valley

• The massive wall of ice at Glacier Grey

• Turquoise lakes, lenga forests, and condors overhead

Every day brings jaw-dropping vistas that change with the light and weather.

🏕 Comfortable Adventure

You don’t have to rough it—refugios offer bunk beds, meals, and hot showers. Some trips even include porters, private rooms, and fully guided support for a smoother experience.

🌎 Sustainable Exploration

The park has strict sustainability policies and limited group sizes. Choosing a small group tour through The Adventure People ensures your trek supports local operations and follows responsible travel practices.

👣 Achievable Yet Challenging

The W Trek is suitable for active travellers—even first-timers—without needing technical climbing skills. You’ll need:

• Decent fitness

• Layered clothing (Patagonia weather is famously wild)

• A good waterproof

• A sense of adventure!

Best Time to Trek Patagonia

The trekking season in Torres del Paine runs from October to April:

• November to February: Peak season with long days and mild temperatures

• October or March/April: Fewer crowds, changeable weather, and beautiful autumn colours

Avoid the winter months (May–September), when most refugios are closed, and trails may be unsafe.

What to Pack for the W Trek

• Base layers and fleece

• Waterproof jacket and trousers

• Lightweight hiking boots

• Refillable water bottle (streams are drinkable!)

• Quick-dry towel and toiletries

• Trekking poles (optional but helpful)

• Passport (yes, even inside the park)

W Trek vs O Circuit

• The W Trek is 4–5 days, focusing on the highlights.

• The O Circuit is a longer 8–10 day route that loops around the entire park, offering a more remote and demanding experience.

If you’re a first-timer or short on time, the W Trek is the best option.
