Tso Lake: Arunachal Pradesh

Arunachal Pradesh, often called the “Land of the Dawn-Lit Mountains,” is one of the most enchanting states in Northeast India. Known for its pristine landscapes, Buddhist culture, and high-altitude passes, the district of Tawang is home to over 100 alpine lakes. Among them, two stand out as jewels of the Himalayas—Sangestar Tso (popularly known as Madhuri Lake) and P.T. Tso (Pankang Teng Tso).

These lakes, situated on the rugged road to Bum La Pass near the Indo–China border, are not only natural wonders but also cultural and spiritual landmarks. At elevations between 12,000 and 13,500 feet, they reflect the raw power of the Himalayas, blending history, local traditions, and natural charm.

This detailed guide explores the lakes, the journey, permits required, cultural backdrop, and everything travelers need to know before setting foot in this extraordinary corner of India.

Tawang: Gateway to the Lakes

Tawang town serves as the base for exploring Sangestar Tso and P.T. Tso. Located at around 10,000 feet, it is known for the famous Tawang Monastery, fluttering prayer flags, and traditional Monpa culture. Reaching Tawang itself is an adventure, with winding mountain roads, snow-clad passes, and breathtaking scenery along the way.

The lakes lie on the road from Tawang to Bum La Pass, which marks the Indo–China border. This route is patrolled by the Indian Army, ensuring safety but also requiring special permits for travel.
