Extreme Snowstorm Claims Five Lives on Torres del Paine’s ‘O’ Circuit

A violent and unexpected snowstorm in Chile’s Torres del Paine National Park has tragically resulted in the deaths of five international hikers. The victims—two Mexican nationals, two German nationals, and one Briton—were caught by the extreme weather while tackling the remote “O” Circuit trek, which loops around the Paine Massif. This incident unfolded abruptly on Monday, November 17th.

The tragedy occurred in the notoriously difficult Los Perros – Paso John Gardner sector. This section includes the highest point on the multi-day trek. The pass is already considered complicated in its natural condition, but it becomes "doubly challenging" during a blizzard.

The region was hit by a sudden, intense deterioration of conditions, despite it being Patagonian spring. Hikers encountered heavy snowfall and wind gusts reaching up to 193 kilometers per hour (120 mph). This force is comparable to a Category 3 hurricane. This phenomenon is sometimes known as “white wind”. Visibility dropped to near-zero, and the terrain became impassable. The combination of severe cold, deep snow, and wind prevented hikers from reaching nearby shelters.

Search and rescue operations were immediately launched by approximately 30 park rangers, military personnel, and specialized teams. However, the severity of the winds and poor visibility made the search extremely difficult. Four other hikers were eventually located alive, and the extensive search was called off after all missing persons were accounted for.

Torres del Paine National Park is a UNESCO World Biosphere Reserve that attracts over a quarter of a million visitors annually. While the area is globally renowned for its high winds and rapidly changing weather—often described as experiencing "four seasons in one day"—fatalities of this scale are rare.

Even during the popular season of November to April, trekkers must be prepared for everything from high winds to snow and ice. Proper layering, high-quality waterproof gear, and being adaptable are not just recommendations; they are critical safety requirements for this remote environment.

This tragic event prompts crucial discussions about backcountry safety. For the adventurous community, this highlights the necessity of situational awareness and conservative decision-making. Hikers must be prepared to turn back when conditions are dangerous, even if it disrupts an itinerary.

The Chilean prosecutor's office has opened an investigation to determine the exact details of the incident. In the meantime, the affected section of the "O" Circuit has been closed by authorities. Our thoughts are with the families, friends, and loved ones of the deceased.
