Avid traveler, loves road trips
hi Rajat, 16 days is good enough. I did drive on snowed roads and its ok in a non 4x4. of course you have to drive carefully. Which part of north east are you planning? My suggestion would be Bhutan or Arunanchal Pradesh or west sikkim. if you are looking more around Himalayas, try Munsyari in Uttarakhand. I did a road trip to that place in Dec 2014 and it was awesome. my next choice would be Bhutan.
