Coombergram is located in the Barak Valley, Assam and is 3 Km from the Kumbhigram Airport. The garden is surrounded by Koomber Tea Garden, Dewan Tea Estate, Pollorbund Tea Estate and Air force Station.

The garden had suffered on a regular basis due to acquisition of land by the Government for construction of the Silcahr Airport, Refugee Colony, Army etc, thus resulting in lack of virgin area for expansion.

The garden is said to have started before the 1880s the only proof being a graveyard in the manager's bungalow of Miss Amy Caroline Bell and an unidentified gentleman. This is still being maintained by the garden. However, records are available only from 1913.

The labourers here are mainly Oriyas, Santals and Adavasis. A very small percent comprises of Muslims, most of whose families migrated from Bangladesh in the 70s.
