Overview
- The suspension covers all high‑mountain tourist activities across the range and bars access to both visitors and tour operators.
- Park authorities set the restriction from December 24, 2025, through March 31, 2026, after technical reports cited new crevasses, ice caves, and forming lakes.
- Inaigem also flagged increasingly variable weather that raises objective risk for climbing and trekking in the area.
- Officials noted an overload of climbing activity, including in restricted zones, which is hindering recovery of fragile high‑Andean ecosystems.
- Separately, Ingemmet designated the Casga population center a critical high‑risk zone after finding unstable soils, 40‑meter slope cracks, and water seepage affecting a community of 115 residents.
