International Mountain Day
One global day to celebrate mountains, adventure, and the wild places that keep life flowing.
What is really behind International Mountain Day
International Mountain Day is the official global observance recognized by the United Nations to raise awareness about the importance of mountains. While some people refer to it informally as International Mountaineering Day, both names point to the same celebration held on December 11. The focus is on recognizing mountains for their role in supporting ecosystems, cultures, freshwater systems, and livelihoods around the world.
Why is International Mountain Day important?
International Mountain Day is important because mountains provide freshwater to more than half of the global population, support nearly half of the world’s biodiversity hotspots, and are home to over one billion people. Mountains regulate climate, store water, and sustain agriculture, making their protection essential for both environmental stability and human well-being.
