So without much ado, here is the reason and result of my 10 day trip: Kolkata-New Jalpaiguri-Darjeeling-Maney Bhanjayang-Dhotrey-Tunglu-Tumling -Kali Pokhari-Sandakphu-Gurdum-Rimbik-Darjeeling-Kolkata!
Journey on the Toy Train: Train leaves from New Jalpaiguri and reaches Darjeeling in about 7 hours! But trust me you won't mind.
Simple! Wasn't it :)
