The Golden Rule
Every gram matters on a multi-day trek where your pack is on your back for 6–9 hours a day. The W Trek is not a wilderness expedition — refugios provide hot showers, cooked meals, and a warm bed. You do not need to carry a week's food or camping equipment unless you are specifically camping. This list is for refugio trekkers.
What to Rent in Puerto Natales
Do not bring from home: sleeping bag (rent a -5°C rated bag for $12–15/night), trekking poles ($5/day), and hiking gaiters ($3/day). These are available from multiple shops in Puerto Natales and renting saves significant weight in your travel bag before and after the trek.
Clothing: The Essential Layers
Patagonian weather is famously changeable — a sunny morning can become a 100km/h windstorm by afternoon. The layering system is essential: moisture-wicking base layer (1–2 tops, 1 bottom), insulating mid-layer (fleece or down jacket), and a windproof and waterproof outer shell. The outer shell must be genuinely waterproof — water-resistant is not sufficient in sustained Patagonian rain.
The Non-Negotiables
These items have no substitutes: waterproof jacket (not water-resistant — waterproof), trekking boots (broken in before the trek, waterproof), warm hat and gloves (even in summer — the Base Torres summit area can reach near-freezing with wind chill), and high-capacity water bottles (3L minimum — the trail is long and hot in summer).
Photography
A smartphone camera takes extraordinary photos on the W Trek — the landscapes are so dramatic that equipment matters less than timing and conditions. If you bring a DSLR or mirrorless camera, pack it in a dry bag inside your pack — rain can appear instantly. Extra batteries are essential; cold temperatures drain batteries 30–40% faster than normal.
What to Leave Behind
Jeans (heavy when wet), cotton anything (takes forever to dry and provides no insulation when wet), more than 2 changes of clothing (refugios have drying rooms), a large towel (refugios provide them, or bring a microfibre one), and any shoes other than your trekking boots and camp sandals.
