Mumbai is India's premiere city. One will see modern Western ways of living comfortably combine with the ancient Indian culture. Expect to see frenetic living, traffic jams and pollution-laden roads during the day, while you can attend by the evening superb classical dance/music events, or visit ancient temples that transport one tens of centuries into the past.
The Juhu beach is minutes away by walk from the Bhaktivedanta Institute campus. Driving two hours from the city, one can escape into the dazzling rain forests at the foothills of Matheran.
