International Mountain Day

International Mountain Day is an opportunity to appreciate the beauty and power of mountains and connect with nature. Mountains have always been of spiritual significance, as evidenced by the many references in ancient mythology. Olympus, Safa, and Meru are some of the most famous examples, each with its own unique story.

History

Mountains have long symbolized eternity, harmony, and spiritual balance. Ancient peoples believed that mountains connected earth and sky and that the souls of the departed found peace in tunnels leading to the underworld. Mythology is full of mountain references, and some of the best-known are Olympus, Safa, and Meru—each named after a real mountain, albeit non-magical.

The goal of International Mountain Day is to explore and appreciate the world’s awe-inspiring peaks. Everest, K2 (Chogori), Lhotse, Manaslu, Fuji—the list is endless. Whether you enjoy an active lifestyle or simply seek knowledge, don’t miss this date!
