I have visited there in January 2018 with my family members. We indeed enjoyed there. The best feeling is when you go through the greeny and hilly areas with the help of Rope way.
And when you reach at the top you find so many collections of Buddha statue, caps, purse and so many things to buy.
Buddha cave temple is so huge and best place there to take a picture with family and friends.
Venu Van park is good place with a big pond with full of fishes and ducks.
Near Rajhgir there is a historical and ancient University of Nalanda. A famous and huge University.
Its a good place to visit every body should visit there. Tourist from Nepal , China , korea , Thailand used to visit there every year in order to meditate and worship with Lord Buddha.
