Ortigia Sea Caves & Plemmirio Marine Reserve Boat Tour
Glide past ancient fortresses, hidden sea caves, and crystal-clear waters on a guided boat excursion from Siracusa.
This Ortigia boat tour combines natural wonders and centuries of history along one of Sicily's most iconic coastlines. Departing from Ponte Umbertino, the route covers sea caves, landmark monuments, and the protected waters of Plemmirio in just two hours.
The journey begins at the small harbour known as Lo Sbarcadero, dedicated to Siracusa's patron saint, Santa Lucia. From there, the boat moves along the coastline to reach three natural sea caves carved into the limestone cliffs, including one whose entrance takes the shape of a heart.
Rounding the eastern waterfront, passengers view Castello Maniace, the medieval fortress that has guarded the tip of Ortigia for nearly eight centuries. The route also passes Fonte Aretusa, a rare freshwater spring that surfaces at the edge of the Ionian Sea and has inspired myth and legend since antiquity.
The highlight of the tour is a swimming stop at the Plemmirio Marine Protected Area, locally known as La Pillirina. The return leg crosses the Grand Harbour, passing back under Ponte Umbertino and offering a final panorama of the city's layered skyline.

Itinerary
The tour departs from the iconic bridge connecting Ortigia to the mainland. The boat heads toward Porto Piccolo, known as Lo Sbarcadero, which is dedicated to the patron saint Santa Lucia.
The boat reaches three natural sea caves formed in the rocky limestone shoreline. One cave is notable for its heart-shaped opening, making it a distinctive point along the route.
Cruising along the eastern promenade, passengers see the full profile of Castello Maniace rising above the water. This fortress has defined the southern edge of Ortigia since the 13th century.
The route passes Fonte Aretusa, a natural freshwater spring embedded in the seafront of Ortigia. According to Greek mythology, the nymph Aretusa was transformed into this spring to escape the river god Alpheus.
The boat anchors at La Pillirina within the Plemmirio Marine Protected Area for a free swim. The protected status of these waters ensures exceptional clarity and marine biodiversity.
The return journey crosses the Grand Harbour and passes back under Ponte Umbertino. This final stretch offers sweeping views of Siracusa's historic waterfront from a unique nautical perspective.
