Amongst the many mountain hot springs in Sikkim, Reshi hot spring is quite popular because of its location and religious significance. Hot Water Springs or Cha-chu  of Reshi are traditional winter spas where visitors and local pilgrims spend a week or more soaking in these springs that are believed to have medicinal properties. This hot spring can be reached after an hr downhill drive towards the Rangit river valley. It is approximately 6 km from Legship. From the road head one has to walk down fifteen minutes to the hot spring site.

This hot spring is located along the banks of the Rangit River and can be visited from December to February. For overnight stays temporary huts are available at nominal rates but all bedding and cooking utensils have to be carried along. During the hot water spring season small shops selling basic vegetables & provisions are setup and the local villagers sell dairy products.

Adjacent to the river is a small monastery and holy cave called “Lho Khandro Sang Phug”, also known as the cave of occult fairies.
