Depart from the ancient village of Aci Castello and board a comfortable 13-meter boat: the ideal vessel for navigating comfortably and safely along nearly 20 km of volcanic coastline. The route winds between the spectacular La Timpa Nature Reserve and the Cyclops Islands Marine Protected Area, offering continuous panoramic views of basalt cliffs, rocky promontories, and small, hidden coves. Refreshing drinks and light snacks will be served throughout the voyage to make the journey even more enjoyable.

The excursion is led by a marine biologist and an underwater environmental guide who will accompany you every step of the way: first with onboard explanations of the area's geology and biodiversity, then with practical tips for snorkeling. You'll be able to observe the extraordinary lava formations up close—basalt columns, rope lavas, and pillow lavas—and understand how ancient volcanic flows and fractures shaped this stretch of coast. The itinerary also includes a passage near the evocative Ulysses Caves, marine cavities that add a touch of myth and mystery to the landscape.

Putting on a mask and snorkel, you'll explore rich and varied seabeds: meadows of seaweed and other brightly colored marine plants, stretches of white sand contrasting with dark rocks, underwater canyons, and rock walls teeming with life. The chances of sightings are excellent: you might encounter curious groupers, schools of white bream, furtive octopuses hiding among the rocks, and various species of sponges and invertebrates that populate the ravines.

Beyond the naturalistic aspect, the experience offers moments of relaxation and photography: stops to admire the profile of the Cyclops Islands from the sea, short refreshing dips, and free time to swim in the quieter coves. At the end of the day, the boat returns to Aci Castello, enriched with new discoveries and unforgettable memories of a unique territory.
