I thought the cave was OK. ( I may be jaded since I've been to many caves in the past) The electricity was turned off so the experience was by flashlight only. I thought that was kind of cool, and my kids loved it. (I think they could have adjusted the rather steep ticket prices considering). There were some very nice curtains, but we couldn't really see some of the features as well as I would have liked. The real problem we had was that our very knowledgeable guide hustled us through the cave very quickly, then stopped for long periods at the 3 main stops to tell us about the different features that we hadn't been able to see.
The road to get to the cave is very long and winding, and it does take quite a while to get there. As has been mentioned earlier, do not attempt the hike to the cave if you are not in decent shape. The trail is pretty short, but very steep. My 5 year old had no problem with it, but her dad was huffing a little.
