They had set out from Gangtok early this morning in 60-odd small vehicles and were to return to the Sikkim capital by the afternoon after visiting Tsomgo.
But soon after they reached Tsomgo, the snowfall intensified and their vehicles could not make a move as the road got covered with snow.
This made the drivers to somehow send out an SOS message to the nearest Indian Army establishment. The Army swung into action at once and rescued the stranded tourists from Tsomgo amidst the continuing blizzard.
The tourists, including women, children, and elderly people were evacuated in Army trucks that are capable of maneuvering through snow and slippery roads.
They were brought to the nearest Army camp at 17th Mile and provided with shelter.
According to a Defence ministry spokesperson, some tourists fell sick due to inclement weather and by the effect of high altitude. They were evacuated in Army ambulances and were offered emergency medical treatment.
The tourists subsequently dropped in Gangtok in Army vehicles. They include people mostly from Bengal and Gujarat.
