Varanasi
In the south east of Uttar Pradesh lies Varanasi, the city of Shiva and one of the most sacred places in India. A centre of learning and devotion for over 2000 years, pilgrims flock here to wash away their sins in the holy Ganges, inspiring reverance and amazement in equal amounts in Western visitors.
The 100 or so ghats - used mostly for bathing but some are also open-air crematoriums - line the western bank of the Ganges. They're best visited by boat at dawn for the best light, although you can easily walk from one to the next. Photographers will delight in a never-ending parade of subjects: people brushing their teeth, selling marigold garlands, engaged in sacred rituals, chanting, swimming, smoking marijuana. There are also several temples to explore, and yoga to practice; best of all is wandering the labyrinth of alleyways in the Old Town.
Varanasi is noted for its silk and beautiful saris, as well as cotton cloth. It's a good place to get clothes made up, but be careful of getting ripped off. You can also buy toys, musical instruments, and carpets.
