The Ministry of Production and Environment of **Tierra del Fuego** has decided to completely restrict access to the **ice caves** located in the **“Reserva Hídrica Provincial Vinciguerra y Valle del Arroyo Chico” Natural Protected Area**, near **Ushuaia**. This is due to the **serious structural risk** they present.
The provision was established by **Resolution MPyA N° 219/25**. The goal is to **protect the lives of visitors** due to the increasing process of **melting and ice detachment** from the glacier, caused by **the sustained rise in temperatures and seismic activity** in the region.
“The glacier front is rapidly losing thickness, with increasing instability in the caves. We invite you to enjoy the surroundings without exposing yourself to unnecessary risks”, warned **Environment Secretary Andrea Bianchi**.
## A rugged environment that requires precautions
Authorities have reminded that this is a **high mountain area**, where hikes should be carried out:
– With appropriate clothing and technical equipment
– In the company of **authorized guides**
– Respecting the **installed signs and current regulations**
Unauthorized entry **compromises both personal safety and the integrity of the glacier ecosystem**, already **affected by climate change** and tourist pressure.
## The precedent of the collapse of Jimbo’s Cave
The decision is part of a stricter prevention policy, following the **collapse that occurred last summer in Jimbo’s Cave**, one of the most visited natural formations in Tierra del Fuego.
Despite being restricted since 2021, unauthorized entry continued irregularly. Researchers from the **Austral Center for Scientific Research (CADIC-CONICET)** had warned about **frequent ice and rock falls** inside the cave, caused by **natural erosion and unregulated tourist use**.
“The collapse, although it did not cause any victims, showed the fragility of these natural structures and the need for more assertive measures for their preservation”, stated from the Ministry.
## A call for conscious tourism and shared responsibility
Authorities urged **tour operators and visitors** to:
– Avoid promoting excursions to high-risk areas
– Respect access restrictions
– Prioritize safety and environmental education
“Passing through the ice caves was almost an obligation for mountaineers and hikers, but today it requires a different approach: that of active conservation and responsible visits”, Bianchi concluded.
