1. Pankang Teng Tso (PT Tso Lake)
The lake PT Tso, as is known by all the residents of Tawang, is the spot of natural union of beauty of the mountains with the expanse of the grasslands. With every week the lake and its surroundings take a different colour and the scene changes significantly. It is not only a lake, it is a dream like imagination because of the splendid views it captures in that setting. The magnificent symmetrical fir forest of the mountains puts a mist of a green glow on the water of the lake. The carpet of the yellow flowers especially of the primula species are found in all the open pockets around the lake and are interspersed by the rhododendron patches,blooming with the grandeur of the mountains forming the background. The pink terraces of the rhododendrons ,the yellow mat of the primulas under the clear blue roof give the lake an unusual pristine beauty. With the advent of winter at the horizon,the blue sky with floating white clouds at the top,the snow capped mountains all around the lake and the embrace of the rhododendron forest give the lake its colour and turn it into a sleeping beauty awaiting the arrival of her beloved.

Stepping into the lap of the nature is always enchanting and challenging. The stream water from the mountains nearby drains into the depression ,creating the water mass ,and a spring also emerges from the lake.
