Dear Alana, thank you for your review. We appreciate your feedback and will take it on board. One thing I wanted to clear up- it seems you may have misinterpreted our tour guide's favourite joke! During our tours we explain that the moisture is NOT glow worm pee, just water. We're sorry that was unclear, we certainly wouldn't want to touch glow worm pee either! Our cave is 98% humidity, so ambient condensation creates moisture on the handrails, but I can assure you it is simply water. We're glad you had a good time even with the miscommunication.
