Located between Nathula and Jelepla pass at an altitude of 13,123 ft and about 52kms from Gangtok, Baba Harbhajan Singh Temple is popularly known as Baba Mandir. There is a touching story associated with this temple. Harbhajan Singh was a Sentry of Punjab Regiment and was posted here as part of border patrol force. The border with China is nearby. In October 1968 he disappeared. It is said that while escorting mules carrying provisions, he fell into a stream and drowned. After a few days he reappeared in the dreams of one of his sentry colleagues and asked him to make a memorial here on his name. The sentries then made a samadhi and later this temple was built.
