The Caves of Ulysses
You only go in when the sea is right.
Two miles south, carved by Etna's lava flows. When the sea allows it we switch off the engine and glide inside in silence. When it doesn't, we don't go in: the sea decides, not us.
It is not a guaranteed attraction and we don't sell it as one. It is the part of the tour you will remember most, when it happens.
