This site was such a surprise - in a completely positive way. I didn't know too much about it beforehand and didn't expect the caves of statues to be so beautiful and inspiring. The design is wonderful and it's such an interesting bit of Buddhist history.
The climb up to the caves can be a little steep at points and there are some quite violent monkeys along the way. But once you're at the top you can easily spend an hour or two looking at everything and exploring the different caves. There's a peaceful atmosphere up the top to rest and let it all sink in.
