The hull rocks gently as Mount Etna outlines the horizon and the first limestone stacks of Aci Trezza appear—black lava cliffs step down to glassy water. You push off from Catania's harbor and the city recedes into a line of ochre buildings and seafront palazzi while the boat slips along a coast carved by lava flows and centuries of surf.

The hull rocks gently as Mount Etna outlines the horizon and the first limestone stacks of Aci Trezza appear—black lava cliffs step down to glassy water. You push off from Catania's harbor and the city recedes into a line of ochre buildings and seafront palazzi while the boat slips along a coast carved by lava flows and centuries of surf.
This stretch of eastern Sicily is geological theatre: repeated Etna eruptions laid basalt and lava that cooled into the ragged coast you see, and medieval watchtowers dot the shoreline—reminders of raids and trade routes that shaped local settlements. The skipper points out Aci Castello’s Norman-era fortress perched on volcanic rock and steers toward sea caves and the iconic faraglioni of Aci Trezza. Culture arrives at the table: a cutting board of cured meats, cheeses, olives and a bottle of prosecco shared as the boat anchors in a calm cove.
Expect two swim stops—one near a cavern often called Ulysses’ Cave and another inside a protected marine reserve—both ideal for snorkeling with guide-provided masks and fins. The trip runs about four hours, suits a broad range of fitness levels, and carries on-board restrooms.
Practicalities: bring reef-safe sunscreen, a lightweight towel and footwear that grips wet decks. Morning departures offer calmer seas and clearer views of Etna; late-afternoon cruises reward you with warm light over the basalt stacks. Follow the guide’s safety brief, avoid standing on rails when moving, and respect marine life—swims are best when wind and swell are low.
Yes—masks and fins are provided and a guide supervises swim stops; you may bring your own gear if preferred.
The boat includes an on-board restroom for passenger use during the cruise.
Yes—non-swimmers can remain on board during swim stops and still enjoy coastal views and the aperitif.
