Both Sikkim and Meghalaya are beautiful. You can visit any place in northeast in winter, everything there is mesmerizing. But if i have to choose between Meghalaya or Sikkim, i would go with Meghalaya.
Hello, Both the places would be good, but Meghalaya looks more beautiful in monsoon, when the waterfalls have enough water flow and the valleys are covered in all shades of green. I would suggest that you take a trip to Sikkim in December :) If you go higher up to Lachung & Lachen, you'd get snow there as well. :)
