The purpose of International Mountain Day is to draw world attention to the critical roles that mountainous regions of our world play. This includes producing food, serving as a source of fresh water, providing a suitable ecosystem for numerous unique species, and providing trekking, mountain climbing, skiing, and other recreational opportunities.

There is also a focus on sustainable mountain development. Logging, mining, and hunting and fishing are all important economic activities that help make mountainous regions important, but unless proper conservation methods are employed, they could prove unsustainable.
