What to Expect from a Trip to Rajgir?

Hey everyone, I've heard a lot about Rajgir and have been considering visiting, but since it's quite far from Madhubani, I want to be sure it's worth the trip. I tend to have high expectations when traveling and get disappointed easily. So far, my trips have mostly been to Uttarakhand and the Northeast, which I really enjoyed. For those who have been to Rajgir, what can I realistically expect from the experience? Is it worth the journey? I'd love to hear your thoughts!
