7. Explorers Glacier, Patagonia, Chile
In 2023, Chilean officials banned hiking on the Explorers Glacier. The decision came after experts noted rapid melting and unstable conditions.
Climate change has made the glacier thinner each year. The formation of meltwater lagoons has increased the risk of accidents for anyone walking on the ice.
Authorities stated that ecotourism activities are no longer safe on this glacier. The ban is now permanent, and hiking is not allowed on the Explorers Glacier.
This closure highlights how environmental changes can quickly make once-popular outdoor areas too dangerous for visitors. The restrictions aim to protect both hikers and the fragile environment.
