The Silk route has been famous among the travelers. It was the transit point from Tibet to India during the times of trading silk between the nations.
We were a group of 5 friends who headed to Zuluk. It is again 150kms from Sikkim. This time we had a friend's car and drove all the way to Zuluk. Remember drives are costlier than other means of travel. If the number of people are few, this should be avoided.
The altitude here rises to 10000ft above sea level making it a chilly place which remains covered in snow from January to April.
We had put up in a homestay at Zuluk costing only 2000 per night including food.
