Fun.
Big cave. Borrow a flashlight. Feet will get dirty, no worries, there are tiny ponds to wash your feet as you walk around.
There are bats. If you like Batman, you'll like this place. Multiple places for good view of the land.
Minimal stair rail, has a bit of danger that adventurers will like. Might not be good for the elderly or young children.
You can ask someone outside the cave to guide you through, they don't charge and they won't impose, but you should probably give them some "snack" money if you enjoyed the time.
There's water dripping throughout.
Bring your ultra low light camera.
