The Tendong Hill is located at an altitude of 8530 ft above sea level. It is a dormant volcano. Folklore has it that the horns raised to rescue people when the land was drowned in floods. Thus it came to be later called as Tendong which locally means "The hill of the raised horn". The Tendong hill was a place where the lamas used to meditate for years.
The hill is a popular trekking destination of Sikkim. The 6 km trek up the hill would take you through thick forests that are rich in flora and fauna.
