After seeing those cases, we walked around the temple and down a set of stairs which takes you into a huge hollow in the mountain. I don't have photos of that because I was sweating like a rapist so kept my phone in my pocket.
I came back from Cambo 5kg lighter and I reckon I lost most of it climbing around this mountain!
At dusk we moved to the base of the mountain where there is a cave renowned for the bats that nest there. The locals have set it up with chairs and bars so you can sit and have a beer and some local food while you are waiting. There is even a nicely constructed bar at one end with a viewing platform so that's where we went.
It's hard to describe, but if you've seen videos of starlings swarming, it's like that. The bats just suddenly start leaving the cave as the light disappears, and stream off into the distance in a massive line which circles from side to side.
It is quite a sight and my paltry photograph does not do it justice. We sat there for 45 minutes and they just kept on coming. As we left they were still streaming out. There are millions of them, quite literally, apparently.
