Sankos Tea garden is located in the extreme eastern end of the Dooars with the state of Assam to its east , Kumargram Tea garden to its west ,the Dumpara forest and subsequently Bhutan to its south and lying above it is the Huldibari busti .

It is served by the Bagdogra airport 270 Kms away .
The garden was established in the year 1895 and owes its name to the picturesque Sankos river which flows through the eastern boundary of the garden . The name Sankos may have been derived from the words Swarn – Kosh meaning gold reserves . If Folklore is to be believed , large quantities of gold lie buried deep in the river bed.
From the past records available to the garden it can be established that the garden originally belonged to the Assam Dooars Tea company under the management of Duncan Brothers and Company .
