Packing for Patagonia can make or break your trip. The weather is extreme and unpredictable: winds of 80-100 km/h (50-60 mph), temperature swings of 15°C in a single day, surprise rain and intense UV radiation due to proximity to the ozone hole. This guide gives you the complete list, from the three-layer clothing system to essential accessories, so you can enjoy every excursion without getting cold, wet or sunburnt.
The layering system: the golden rule
Base layer (first skin)
Synthetic or merino wool t-shirts and leggings that wick moisture and keep you dry. Avoid cotton — it retains moisture and chills you quickly. In summer, a lightweight thermal base is enough. In winter, heavy merino or thermal base layers are essential.
Mid layer (insulation)
Fleece (200-300g) or packable down jacket for heat retention. A mid-weight fleece handles most Patagonian conditions. For winter or high-altitude treks, a compressible down jacket adds crucial extra warmth.
Outer layer (protection)
Waterproof, windproof jacket with sealed seams. This is the single most important piece of Patagonian gear. Wind penetrates anything that is not specifically windproof, and horizontal rain is common. Invest in a good membrane jacket (Gore-Tex or equivalent). Do not skimp on this item.
Footwear
- Waterproof trekking boots: broken in before the trip. Vibram or equivalent sole with good grip.
- Comfortable trainers: for city walking and rest days.
- Flip-flops/sandals: for hostel or hotel.
Essential accessories
- Sunscreen SPF 50+: UV radiation is extreme due to the ozone hole. Reapply every 2 hours, even on cloudy days.
- UV-protection sunglasses: that fit snugly so wind doesn't blow them off. Strap recommended.
- Hat or buff: sun protection in summer, warmth in winter.
- Gloves: essential May-October. Useful year-round for glacier excursions and early mornings.
- Neck gaiter/scarf: multi-use for neck, face and head.
- Day pack (20-30L): for water, food, spare layers and camera on excursions.
- Reusable water bottle: Patagonian spring water is clean and delicious.
- Trekking poles: optional but highly recommended for El Chalten, Laguna Esmeralda and mountain treks.
Electronics & documents
- Power bank: no cell signal on many trails but camera and GPS drain battery.
- Offline maps: download maps.me or Google Maps offline. No signal on Route of the Seven Lakes, El Chalten, Tierra del Fuego or most trails.
- Plug adapter: Argentina uses Type I plug (three flat angled pins). European, US and UK travellers need an adapter.
- Waterproof camera case: for glacier and boat excursions.
