Exploradores Glacier, Glacier in Laguna San Rafael National Park, Aysén Region, Chile

Exploradores Glacier is a glacier on the northeastern slope of Monte San Valentín, in Chile's Aysén del General Carlos Ibáñez del Campo Region. It lies within Laguna San Rafael National Park, and the nearest locality is Puerto Río Tranquilo, on the western shore of General Carrera Lake.

On 6 October 2023 a large block of ice fell from Exploradores Glacier. After a two-week study, Chile's National Forest Corporation declared on 31 October that the glacier carried "evident risks" and that conditions were unsafe for ecotourism. Trekking routes closed, then reopened on 2 February 2024 along a new route with stricter requirements for visitors and guides.

Local guides and adventure operators from Puerto Río Tranquilo work on the glacier, and their reaction to the October 2023 closure shaped how it is used today. Chile's National Forest Corporation reopened trekking on 2 February 2024 along a new route, with stricter requirements for visitors and guides.

The best visiting window is between October and March when conditions are most favorable for travel. Access requires proper preparation and gear suited to high-altitude mountain weather and unpredictable conditions.

On 6 October 2023 a large chunk of Exploradores Glacier collapsed, prompting Chile's National Forest Corporation to declare on 31 October 2023, after a two-week hydrologist study, that conditions were unsafe for ecotourism.
