Budget: Northeast is costlier than many other parts of the country. In hilly and remote areas Tata sumo or other such vehicles are used in shared basis for commutation. Fares on such vehicles are higher than bus or the prices charged in plains for the same distance. Even foods cost more on hills. But if you choose to cover mostly the plains of Assam, Tripura or Arunachal Pradesh you will get better modes of commutatioatth cheaper price. In the plain areas hitchhiking opportunities will also be more. Deciding the route: Since North East comprises of eight states it is advisable to decide the states and places you want to cover beforehand. It will help you to research the places and duration of your trip. It is also important because for entering in Nagaland, Arunachal Pradesh and Mizoram you will need to obtain Inner Line Permit. Best time to visit: The best time to visit North East is from October to April. During summer season rain causes a flood as well as a landslide, I am sure you would not like to stuck in a natural deserter like that. You can consider a trip in April as it is the best time to see the flowers blossom on the arrival of spring. Sikkim and Arunachal are the best places to see them. Starting from September, every year many festivals are organized throughout the northeast, (eg: zero music festival, orange festival, a kameng river festival, monolith festival etc) if you plan your trip accordingly you will get to meet many fellow travelers like you.
