P.T. Tso Lake (Pankang Teng Tso)

P.T. Tso Lake, also known as Pankang Teng Tso, is a high-altitude natural lake in Tawang district of Arunachal Pradesh, about 17 kilometres from Tawang town at an elevation of around 3,800 metres. Surrounded by snow-capped mountains, rhododendron slopes and alpine meadows, the lake is known for its clear waters, seasonal frozen surface in winter and scenic Himalayan setting, making it a popular sightseeing stop on the route toward Sela Pass and Bum La.

Visitors can expect a high-altitude Himalayan lake with clear blue water set amid rugged mountains, alpine meadows and rhododendron-covered slopes. The site is open and exposed with panoramic views, yak grazing areas nearby, and photo points along the roadside. There are no boating facilities; the experience is primarily sightseeing, photography and short walks around the lakeside in cold, windy conditions.
