This is a fun cave visit. Its located next to an observatory that you could combine in the same trip. When we were there, there was a huge event on with a stage, bands, comedians and a lot of food stalls. But I am sure thats not the normal case.
Honestly, I don't think the caves are so good. At least the formations are fairly tame compared to what we have seen before. But it was fun because the pathway becomes very restricted in parts and you have to crawl and scramble to get past some bits. It might be a bit scary for even mildly claustrophobic people.
