Between the Nathula and Jelepla passess lies Baba Harbajan Singh Memorial Temple built in the memory of Harbajan Singh (30th August1946-4th October 1968), a sepoy in the 23^rd Punjab Regiment. The legend has it that he appeared to his colleagues in a dreams a few days after he went missing while patrolling the border, and informed them about way to find his body and expressed a desire that a Samadhi be built in his memory, which over the years acquired the status of a pilgrimage site, built near Chhokya Chho at an elevation of around 4000 meters, which gained  popularity as the old Baba Mandir. Devotees leave a bottle of water, which they collect a few days later to take back home blessed by the spirit of this hardy soldier. This Samadhi is less visited by  tourist. Visitors need to climb 50 stairs to reach the  bunker, site were the Samadhi has been built. This was the place where  Baba was posted during his service with Indian Army. However, for the tourists convenience, the Samadhi of Baba Harbajan Sing has been reconstructed  at the junction of  Kupup  Gnathang road and the trail leading to  Memencho Lake, the shrine is recognized by the tourist as new Baba Mandir.
