Fantastic experience, loved every moment of it!
The rappelling is a really unique experience, the cave is impressive and the all place is almost unreal.
Safety is always very well taken care of, we had a person in our group who never rappelled before and he had no trouble at all(so don’t let that scare you, you would miss big!), the guide was always supportive and engaging.
Glow warms show at the end of the trek inside the cave.
Climbing back up from the ladder was also great, there was absolute no rush so I could stop a couple of times to admire the rock formation or simply to look down into the abyss:)
I would (and will)definitely do it again.
