In 2010 I visited North Sikkim for the first time, with my college friends. I used to ride a bike then and from that time I dreamt about riding to North Sikkim. Time has passed and I shifted from bikes to cars, but the dream was still there. Many people have been to Leh and other places but very few could manage to North Sikkim. And to be honest I hardly know 2 or 3 people who has done the full circuit in their cars. Not because its tough, because there are certain rule by Sikkimese Govt which doesnt allow private vehicles. But they do allows bikers. So cheer up if you want to ride !!!
