Darjeeling, in the north of West Bengal, is one of the most enchanting hill stations in India, steeped in British colonial history. When I think of Darjeeling, I imagine emerald-green tea plantations, lengthy scenic walks (complete with a home-made picnic) and, of course, the snow-capped Himalayas acting as a perfect backdrop against the deep-blue sky. I also think of the totally serene, privately run Glenburn Tea Estate, which lies in the shadow of Kangchenjunga, the third-highest mountain in the world.
