Visiting Varanasi and Calcutta is a strong experience . Varanasi is unforgetable for its atmosphere , it is really a place that moves you and you have to take time in this old city . a city that you visit from its roofs and through its narrow streets where cars can't pass . Any time of the day , any month , this is the city of religiosity and fervor . Calcutta is a huge city with crowds , pollution and noise , but this is life everywhere . Amid beautiful colonial era buildings , ugly things too , decay , but people that work as much as they can to feed their families , many immigrants from the countryside or from Bangladesh .
