In the heart of Bihar lies the Rajgir Wildlife Sanctuary (36sq km), bordered by a stretch of small historic hills associated with Jain and Buddhist history. A typical monsoon climate prevails over this region full of tropical dry deciduous forests. The sanctuary is rich in leopards, hyenas, barking deer and nilgais. The neighbouring Gautam Buddha Sanctuary (259sq km) in Gaya has similar climes. Further south, en route to Hazaribagh is the Koderma Wildlife Sanctuary (177sq km) situated on the Patna-Ranchi highway. Besides its rich wildlife, the place is famous for its scenic beauty. The most popular one amongst these is the Fhwajadhari Hillock.
