Varanasi or Kashi - The center of attraction for spirituality, religion, music, trade, politics, some great street food & an excellent sense of humour.
The holiest city for the Hindu community (Sanatan Dharma) about which the famous author Mark Twain has rightly said " Banaras is older than history, older than tradition, older even than legend and looks twice as old as all of them put together. "
Varanasi has so many things to offer like temples, ashrams, holy Ganga river, Ganga Aarti, ghats, street food, festivals, etc.
