Darjeeling is one of the most famous tourist towns in India. People travel here from all over the country and the world to enjoy the scenic views and clean mountain air. However, not many realise that with a population density of over 11,212/sq kms (according to 2011 census), Darjeeling municipality is the most crowded mountain regions in the world. By this measure, the population density is greater than New Delhi. This, coupled with the fact that Darjeeling attracts the most number of tourists every year in the Eastern Himalayan region, has made this once gorgeous mountain town one of the most polluted as well.
It thus comes as no surprise that in a recent nationwide cleanliness survey conducted by the Union Housing and Urban Affairs Ministry, Darjeeling featured among the 25 dirtiest cities of India.
