Varanasi (http://www.varanasi.nic.in), once known as Benares or Banaras and Kashi, is a historical city in northern India. The city is sacred to Hindus and also one of the oldest continuously inhabited cities in the world. In many ways Varanasi epitomizes the very best and worst aspects of India, and it can be a little overwhelming. However, the scene of pilgrims doing their devotions in the River Ganges at sunrise set against the backdrop of the centuries old temples is probably one of the most impressive sights in the world. Some people believe that Varanasi is a must see destination on any trip to northern India. Others do not find it particularly interesting to see Hindus bathing themselves in the Ganges, and are turned off by the feces that floods the Ganges and covers the alleys of Varanasi.
The city can be scorchingly hot in the summer months so, if possible, time your visit to fall between October and March, and bring something warm to wear for chilly days and nights, instead.
