Aci Trezza & Aci Castello in one sentence: Two coastal towns north of Catania on the Riviera dei Ciclopi – famous for the Faraglioni dei Ciclopi (the basalt “Cyclops islands”) off Aci Trezza and the Norman castle of black lava stone in Aci Castello. Ideal for swimming and half-day trips with a dose of myth and sea views; less so for anyone after sandy beaches. Allow a half day per town, easily reached by bus from Catania.
North of Catania, the Riviera dei Ciclopi – the “Cyclops Coast” – runs along the east coast. It owes its name to the striking basalt rocks that rise from the sea off Aci Trezza. The landscape is shaped by volcanic activity: black lava stone meets deep blue water, with small fishing towns and rocky coves in between.
In Aci Trezza stand the Faraglioni dei Ciclopi, a group of basalt rocks off the coast. In myth, these are the boulders the blinded Cyclops Polyphemus hurled after the fleeing Odysseus. The town gained literary fame through Giovanni Verga’s novel “I Malavoglia”, which depicts the hard life of fishing families.
A few kilometres south lies Aci Castello with its landmark: a Norman castle of black lava stone perched on a rock right by the sea. Swimming at both towns is mainly from rocky coves and lidos – classic sandy beaches are not to be found here. Both towns are compact and easy to explore on foot; they’re comfortably reached from Catania by bus.

The highlights in detail
Faraglioni dei Ciclopi & Aci Trezza
The Faraglioni dei Ciclopi are a group of steep basalt rocks rising from the sea off the coast of Aci Trezza. Geologically, they are remnants of volcanic activity; in myth, however, they are the rocks the blinded Cyclops Polyphemus hurled after the escaping Odysseus. The largest of the rocks, Isola Lachea, is part of a protected marine area. Aci Trezza itself is a lively fishing town, its atmosphere immortalised in literature by Giovanni Verga in his novel “I Malavoglia”. In summer, small boat tours to the rocks are offered from the harbour.
Castello di Aci Castello
The landmark of Aci Castello is its castle of black lava stone, standing on a rock right above the sea. The fortress dates back to Norman times and impresses above all through its setting: dark volcanic rock against blue water, with a panoramic view of the coast and the Faraglioni in the distance. A short climb leads up to it; inside there’s a small museum. The visit itself is modest, and for many the photogenic view from outside is already the real reason to come.
Swimming & getting there
Swimming on the Riviera dei Ciclopi is mainly at rocky coves and lidos – there are no classic sandy beaches here. The water is usually clear, and you get in via rocks or lido platforms; water shoes are advisable. Getting there is straightforward: bus line 434 runs from central Catania along the coast, stopping in Aci Castello and Aci Trezza. A car gives you more flexibility, but parking near the towns is scarce in summer. It’s worth checking the timetable and season in advance.
Common mistakes
- Expecting a sandy beach – swimming is from rocky coves and lidos.
- Coming without water shoes – getting in over the rocks is otherwise uncomfortable.
- Driving in high summer and underestimating the long search for parking.
- Visiting only one of the two towns – they lie close together and complement each other.
- Skipping the small boat tours to the Faraglioni, which offer the best view.
Alternatives nearby
- Catania – the lively Baroque city at the foot of Etna, just a few kilometres south.
- Acireale – a Baroque town north of the Riviera, known for its carnival and spa waters.
- Etna – Europe’s largest active volcano, clearly visible from the coast.
- Beaches south of Catania – for anyone after a genuine sandy beach.
