Most visitors to behar are inevitably drwn to Bodhgaya, where Prince Gautama Siddhartha is said to have attained enlightenment and went on to bring Buddhism to the world. As such this is one of the most important pilgrimage towns for Buddhist the world over. The famous Mahabodhi Temple and it's Bodhi Tree where Buddha is said to have meditated are a important feature of tourism in Behar.
The trail doesn't stop ther however and there are several other important sites sprinkled around the state, like Rajgir which was the capital of the Magadh Mahajanpad (State) when Patliputra was not formed. In those days it was called Rajgrih. Rajgir or Rajgrih means the home of Royalty. This place has long been associated with Lord Buddha and Buddhism.
The remains at Nalanda are also worth the time, the ruins at this ancient seat of learning are quite extensive.
Vaishali is where the Bhudda is thought to have offered his last sermon, To commemorate the event, Emperor Ashoka, in the third century B.C. erected one of his famous lion pillars here.
For a look into an entirely different faith visit Pawapuri, or Apapuri, 38 kilometers from Rajgir and 101 kilometers from Patna, here all sins end for a devout Jain. Lord Mahavira, the final Tirthankar and founder of Jainism, breathed his last at this place, and was cremated here around 500 B.C..
A visit to the famous Elephant Mela at Sonapur is something your unlikely to forget!!
So travel with care in this often lawless state but Do go.
