The road from tashi view point to Phensang was quite terrible because of rains and landslides.
However remote the area may be u can be rest assured that one companion will always be with u that is Indian Army.
After 100 km of journey we reached Chungthang the origin of river Teesta.
And this was an effort to give some relaxation to the whole body :)
