Interesting day trip from KL
This can be summed up as lots of statues of Hindu gods and shrines erected in an enormous, humid limestone cave.
Overall, I'm glad I went, but since I don't have much knowledge of Hinduism or it's art, so I don't think I could really appreciate it fully. Also, the exhibits don't do a great job of explaining the significance of the figures.
However, the cave itself was really interesting. Large and imposing, you've got to climb up a bunch of stairs to enter the cave. There were a bizillion pigeons in the cave (which was a bit yucky) but also dozens of friendly, mischievious monkeys (which was pretty cool!).
