Visit Pemayngtse, one of the largest and most treasured Buddhist monasteries in Sikkim and India as a whole. Founded by Lama Lhatsun Chempo in 1705, the monastery was built for ta-tshang monks of pure Tibetan lineage who were celibate and without any physical abnormality. It’s a fascinating visit.
Then you will head to the ruins, of Rabdentse, once the second capital of Sikkim. Long destroyed by Bhutanese and Ghurka invasions, the ruins that remain offer a fantastic vantage point from which to enjoy stunning views of Khangchendzonga mountain.
