Very well organized. My father has difficulty walking. Getting on and off the boat went smoothly. The cave itself has many stairs. Otherwise, it is easy to navigate. Very busy. Even in the early season. But that doesn't matter for visiting the cave.

The boat trip to the grotto was lovely, and the time was adhered to precisely.
So everything is fine.
