A cradle-shaped glacial amphitheater in Govind Pashu Vihar National Park, famed for ancient wooden villages, the cradle of the Pandavas, and Swargarohini views.
Nestled deep inside the Govind Pashu Vihar National Park and Sanctuary in western Garhwal, Har Ki Dun ("Valley of Shiva") is one of India's most legendary river-valley treks. Following the roaring Supin River through dense pine, deodar, and chestnut forests, this trail connects centuries-old wooden hamlets where traditions have remained untouched for millennia.
According to Hindu mythology, Har Ki Dun is the path taken by the Pandavas on their ascent to heaven via the formidable Swargarohini staircase of peaks. Along the trail, villages such as Osla and Taluka feature ancient carved wooden architecture, including the unique multi-tiered Duryodhana/Someshwar temple.
At the head of the valley at 3,566m, the wide amphitheater opens up to reveal the massive face of Swargarohini I, II & III, Bandarpoonch, and the Jaundhar Glacier moraine. Har Ki Dun is also a birdwatcher's delight, rich in Himalayan monals, bearded vultures, and golden eagles.
Trekkers are reminded to stay properly hydrated with a minimum of 3-4 liters of water daily. Uttarakhand forest regulations strictly forbid single-use plastics and campfires outside designated grounds. Always pack out non-biodegradable waste.
Along the ridgelines and summit ascents of Har Ki Dun Trek, trekkers are treated to sweeping views of legendary Garhwal & Kumaon summits:
