I am thinking of travelling to Sikkim and Darjeeling next year during summer holidays of my son by my own car. My sole purpose is to explore sikkim, spend some time there enjoying nature and exposing my son to beautiful vistas of Sikkim. Kindly let me know is may an appropriate time to visit. Is travel by own car feasible. What all places I can cover in a span of 7-8 days. Not itinery or route has been finalised.Stay options available with parking facilities for my car is also required. I would like to travel to places which are not there on the usual circuit and spend some time in the countryside.
