Location

Tonglu is located at [ ⚑ ] 27°02′N 88°05′E / 27.03°N 88.09°E / 27.03; 88.09.[5]

Area overview

The map alongside shows the northern portion of the Darjeeling Himalayan hill region. Kangchenjunga, which rises with an elevation of 8,586 metres (28,169 ft) is located further north of the area shown.[6]Sandakphu, rising to a height of 3,665 metres (12,024 ft), on the Singalila Ridge, is the highest point in West Bengal.[7]In Darjeeling Sadar subdivision 61% of the total population lives in the rural areas and 39% of the population lives in the urban areas.[8][9]There are 78 tea gardens/ estates (the figure varies slightly according to different sources), producing and largely exporting Darjeeling tea in the district. It engages a large proportion of the population directly/ indirectly.[10]Some tea gardens were identified in the 2011 census as census towns or villages. [11]Such places are marked in the map as CT (census town) or R (rural/ urban centre). Specific tea estate pages are marked TE.

Note: The map alongside presents some of the notable locations in the subdivision. All places marked in the map are linked in the larger full screen map.
