I've been visiting Itanagar quite regularly in my vacation and almost each time I hate it. The road conditions are very bad, hotels are very costly and most important for touring is sightseeing, which is also not that good. It's environment is quite polluted, air's are polluted. Travelling around is difficult since it is too costly and there's no uber or ola facilities around. But one thing was good i.e. it was safe to tour around.
Overall I didn't liked it.
