One of the main reasons that people come to Lachungvillage is to continue on the same route to witness the most amazing valley of Yumthang which starts around 10 km further from Lachung and extends up to several other kilometers. It is also the entry point to the Singba Rhododendron Sanctuary where you can enjoy the hiking trails and get out of the jeep to witness the wild beauty.
In the spring time and early summer there are around 24 species of rhododendrons and many other flora species that burst in to the flowers. There are a number of shops that usually remain open in the peak season only. There is a river flowing across which will not only make the view more pleasing but also has hot springs nearby. From Yumthang one can continue to 14kms to the snowy mountains of Yume Samdong which is located at an altitude of 4640m. This is where the boundary towards Tibet starts. One cannot go beyond this point, which is also called as Zero point. The road often gets blocked in the month of October due to heavy snowfall and opens again in March only. The valley is quite astonishing and one should not miss it if they are willing to travel that far along the altitude.
