Finally the Indian government lifted the restricted access permit for North East states of Nagaland, Manipur and Mizoram. Getting to these places use to be such a pain as tourist permits to these places involve hideous red tapes or irritating tourist companies that charges you incredible amounts for the permit fee. This is with the exception of Tripura and Arunachal Pradesh which they still consider as sensitive border areas to Bangladesh and China.
If you ever dream of visiting these elusive and mostly difficult places, I strongly suggest to abandon all your other travel plans and race yourself to these states before the other tourists erode the whole place or even much worse, the ever erratic Indian government decides change its mind.
The Indian govt previously permitted independent travellers to Arunachal Pradesh (2 to a group instead of 4) without a state approved guide and had changed it due to the politicking of the Arunachal tourist association.
To independent travellers : Rest assured this will happen to Nagaland, Mizoram and Manipur that erratic changes will be implemented, so visit these places as soon as possible. In case you are visiting these places, be sure to print out all the various newspaper articles on the permits issues and be prepared to show them to the border guards as they would surely not be updated on such news. This comes from experience.
