A challenging 12-day Himalayan expedition from Manali to Bir–Billing, crossing the spectacular Kalihani and Thamsar passes through remote valleys, alpine meadows and the rugged wilderness of Bara Bhangal.
Overview
A challenging expedition into one of the most remote inhabited valleys of the Indian Himalayas, the Bara Bhangal Trek traverses rugged mountain terrain, high-altitude passes, alpine meadows and traditional shepherd trails connecting the Kangra Valley with the remote Bara Bhangal region and Kullu.
Known for its dramatic Dhauladhar scenery and demanding mountain crossings, this trek offers an extraordinary wilderness experience through forests, glacial streams, rocky ridges and isolated settlements. The journey is especially rewarding for experienced trekkers seeking remote Himalayan landscapes, traditional mountain culture and a true expedition-style adventure.
