💡Key Takeaways

Plan for 5 days/4 nights self-guided, booking refugios or campsites early.

Combine with Argentine parks for extended Patagonia adventures.

The W-Trek forms a W shape across Torres del Paine National Park in Chilean Patagonia, linking the park's top sights: granite Torres towers, French Valley, and Grey Glacier. Spanning 70-80 km with 2,100-2,700m elevation gain, it's doable in 4-5 days for hikers in good shape. Unlike the full O-Circuit, it focuses on highlights without remote backcountry.

**Day 1:** Puerto Natales to Chileno via Base Torres (13-18 km, 8 hrs). Climb through forests and moraine to the towers' base—stunning payoff.

**Day 2:** Chileno to Francés/Los Cuernos (15 km, 4-5 hrs). Steady descent with lake views.

**Day 3:** Francés to Paine Grande via French Valley (explore hanging glaciers).

**Days 4-5:** Paine Grande to Grey Glacier, optional boat back (total ~74 km).

Book refugios/camps via park sites or operators like Fantástico Sur—spots fill fast. Good boots, trekking poles, and waterproof gear are musts for steep, muddy trails and winds.

Layer for rapid changes: base, fleece, shell jacket. Carry snacks, water filter, and park map. Fitness: Train for 8-hr days with elevation.

Icons include Torres lookout, French Valley miradors, and Grey Lake icebergs—wildlife like guanacos adds magic. Challenges: Crowds, erosion, and Patagonian gales; go early season for solitude.

Pro tip: East-west flow builds to glacier climax; self-guided saves money but needs planning.

Start from Puerto Natales; use shuttles/boats. Respect Leave No Trace—park is UNESCO reserve. Extend to Argentina's Los Glaciares for full Patagonia immersion.

⚠️Things to Note

Trails are busy; book 6-12 months ahead, especially high season (Nov-Mar).
Weather is extreme—wind, rain, snow possible anytime; no technical skills needed but good fitness essential.
Park entry fee required; start from Puerto Natales with transfers.
Erosion from footfall; consider O-Circuit for quieter paths.
