Nagaland is bordered by Assam Manipur and Myanmar filled with an history from Naga people. This state is full of north east part of Himalayas, on Brahmaputra valley. The city of Nagaland has one of the best weathers all through the year, and now being summer it’s cool with chill air blowing. Mokokchung, Tuensang, phek, japfu peak, Shilloi lake are some best places to visit. On the other hand Mizoram is called as song bird of India filled with calm serene atmosphere. The weather of Mizoram is warm though not much sweaty. Summers that’s now is an ideal time to visit. Serchhip, lunglei, Mamit, kolasib, vantawang falls are some lovely spots. Definitely I would suggest Nagaland as one of the best spot to plan a solo trip. Since the distance between Aizawl and Kohima is 17 hrs drive, based on your travel plans we if it is possible to cover both the states.
