Bali Pass Trek — Complete Guide
Introduction
Bali Pass is the 'Grand Crossover' of the Garhwal Himalayas, a high-altitude bridge that connects the lush Har Ki Dun valley to the sacred Yamunotri valley. Reaching an elevation of 16,207 ft, this trek is not for the faint-hearted. It is a journey of extreme contrasts: starting from the ancient wooden villages of Sankri and Osla, winding through the pristine alpine lake of Ruinsara Tal, and culminating in a technical, 60-degree descent on snow and scree into the Yamunotri basin. Bali Pass is an expert-level test of endurance and technical skill, offering a rare close-up of the Swargarohini massif and the formidable Black Peak (Kalanag). For those who conquer its vertical wall, it is a definitive Himalayan achievement.

Bali Pass is a multi-valley crossover and requires permits from two different forest ranges: Govind Wildlife Sanctuary (Sankri side) and the Yamunotri Forest Division. Permits are issued at the Netwar gate and registration at the Sankri and Janki Chatti police posts is mandatory. Indian nationals need a valid photo ID and a medical fitness certificate. Foreigners must provide passport/visa copies. Due to the technical nature of the pass, forest guards may occasionally check for specialized gear (microspikes/ropes) before allowing the crossing.
