The Honest Pitch
Patagonia has a reputation for difficulty that it has earned honestly. The wind is not a figure of speech — summer gusts in Torres del Paine regularly exceed 100 kilometres per hour on exposed ridgelines, and the weather changes without warning from full sun to horizontal rain to snow and back again in the space of an afternoon.
The Honest Pitch

The wind is not a figure of speech — summer gusts in Torres del Paine regularly exceed 100 kilometres per hour on exposed ridgelines, and the weather changes without warning from full sun to horizontal rain to snow and back again in the space of an afternoon. The trekking season lasts five months. The W Trek and O Circuit require advance booking many months ahead for peak dates.

Most serious Patagonia trips cover both Chilean and Argentine sides. The bus between Puerto Natales (Chile) and El Calafate (Argentina) takes 5 to 6 hours and runs several times weekly in peak season — book in advance in summer. A rental car is useful for the El Calafate and El Chaltén corridor but is not recommended for Torres del Paine, where park shuttles and catamarans serve the trekking infrastructure. Punta Arenas and Puerto Natales are best navigated by shuttle or taxi rather than rental car.
Seasonal Conditions
When to visit
Bar height = overall visitability. Color = conditions tier.
The W Trek booking window for the peak season opens in early April through Vertice Patagonia and Las Torres Patagonia. Popular dates in January and early February sell out within days. If you are planning a December or January W Trek or O Circuit, set a calendar reminder for the first week of April and book the day the window opens. There is no walk-up option — all accommodation must be reserved in advance.
March and April for Wildlife, Not Trekking
The shoulder season from March through April is when puma tracking reaches its peak. Guanaco herds move to lower ground, summer hikers have cleared, and the cats are active in the open steppe in morning light. Autumn colour on the lenga beech forests peaks in April. These months are not good months to do the W Trek — most trails close at the end of April — but they are arguably the finest months in Patagonia for wildlife and photography.

Full season — W Trek and O Circuit at maximum accessibility and longest days
Up to 17 hours of daylight — evening light on the Torres until 10pm
All accommodation, catamarans, and park services fully operational
Wildlife abundant across the park
Workable
The busiest month of the year — W Trek fully booked, accommodation scarce without advance planning
Popular dates sell out within days of April booking window opening
Skip
Last-minute booking — December accommodation books out 6 to 9 months ahead
The W Trek in December delivers the longest days and the peak of the Patagonian spring — wildflowers, abundant wildlife, and 17-hour days that allow evening hikes to viewpoints that are in darkness by 6pm in March. Book in April when the season opens, not in November when it is too late.

02
Pack for all four seasons — every day
Patagonian weather changes in minutes, not hours. A clear blue morning can become a full whiteout by noon and return to sunshine by 3pm. Wind gusts on exposed sections of the W Trek regularly exceed 100 km/h in November and December. Every day in the park requires waterproof outer layers, warm mid-layers, sun protection, and wind gear regardless of the forecast. The forecasts in Puerto Natales are not reliable for conditions inside the park.
Waterproof Everything

Most trips should cover both Chile and Argentina
Torres del Paine and Los Glaciares National Park are separated by 5 to 6 hours by bus and are complementary rather than competing destinations. Torres del Paine is the finest multi-day hiking in South America. Perito Moreno Glacier and the Fitz Roy day hikes from El Chaltén are genuinely different experiences that reward the border crossing. Most serious Patagonia trips of 10 days or more cover both. Fly into Santiago, out of Buenos Aires — or vice versa.
