💡Did You Know?
🔹 Har Ki Dun is called the “Valley of the Gods.”
The name literally means “Valley of God Shiva”, and it's believed that the Pandavas from the Mahabharata took this path on their final journey to Swargarohini — their stairway to heaven.
🔹 You get a clear view of the mythical Swargarohini peak.
Swargarohini I, II & III dominate the skyline and are deeply associated with the Mahabharata legend. On clear days, the view from Har Ki Dun is truly divine.
🔹 The villages here are frozen in time.
Remote villages like Osla and Gangad still retain their centuries-old wooden houses, unique temples, and traditional lifestyles of the local Garhwali people.
🔹 Osla Temple is dedicated to Duryodhana, not a hero!
The intricately carved temple in Osla is said to honor Duryodhana, the controversial Kaurava prince. Locals worship him as a deity — a cultural twist that surprises many trekkers.
🔹 The trail is part of an ancient Indo-Tibetan route.
Long before modern trekkers arrived, Har Ki Dun was used by traders and shepherds moving between the Tons Valley and remote parts of Himachal and Tibet.
🔹 Flora and fauna are rich and protected.
Located inside the Govind National Park, this trail is home to musk deer, barking deer, Himalayan monals, and dozens of wildflower species in spring and summer.
