Hi, Some places to explore in Bihar: - Barabar Caves (oldest surviving rock cut caves)
- Golghar - Patna Museum - Mahabodhi temple - Patna Sahib - Nalanda
Bihar has a lot to offer but what the tourist wants is upto him or her. As it is a historical place so Buddhist sites are also there. The nature trails are also there, kindly be sure and program accordingly.
