Tumsong Tea Estate originally belonged to a German planter JA Wernicke who also owned the nearby Lingia estate. It was then a 200 acres garden. Over the years and after the Chamong group took over, it has grown to a sprawling estate of 186 hectares out of which 114 hectares are used for tea plantation. The rest are factory, office and retreat areas. There are close to 500 workers involved in tea plucking and processing. The tea estate is surrounded by the gorgeous Himalayan mountains and you get magnificent view of the Kanchenjunga from here. The rolling deep green tea plantation is laid on an open hill slope that has an altitude varying between 5,500 ft to 2,700 ft. This is a bio-organic garden and has high concentration of fine China tea bushes. The flowing cool breeze helps to grow the bushes gradually and saturate slowly, thus offering a special flavour of tea. There are several other tea gardens around Tumsong including Lingia, Marreybeong, Mem, Chungthong etc.
