Norman castle on a black lava rock at Aci Castello, the Isole Ciclopi marine reserve and the sea stacks of Aci Trezza, the setting of Verga's novel I Malavoglia.
Aci Castello and Aci Trezza lie along the Riviera dei Ciclopi, about 9 to 11 km north of Catania on Sicily's Ionian coast. AMTS bus line 534 runs year-round from central Catania, roughly 06:00 to 22:40, and takes about 30 to 40 minutes to reach Aci Trezza. A summer line 935 from Piazza della Repubblica also serves Aci Castello and the Scogliera. The urban fare is listed at EUR 1.40, and the fare for the Aci Castello zone should be confirmed at amts.ct.it. Drivers can take the SS114 in about 20 minutes, but parking is limited in summer.
Aci Castello is dominated by a Norman castle built on a black basalt lava rock above the sea, now housing a small civic museum. The surrounding lava coast has rocky bathing platforms and small harbours. Further north, Aci Trezza faces the Isole Ciclopi, a group of sea stacks protected as a marine reserve, which legend links to the giants thrown by Polyphemus at Odysseus. The village is also the setting of Giovanni Verga's novel I Malavoglia, and its fishing harbour keeps that atmosphere. Boat tours around the stacks leave the harbour in season.
A suitable day begins with the morning bus to Aci Castello to visit the castle and walk the seafront, then continues on foot or by bus to Aci Trezza by midday. Lunch in the harbour area is built around fresh fish, spaghetti with sea urchin or sardines, and granita with brioche. The afternoon can go to a boat trip, swimming from the rock platforms or a walk along the promenade, finishing with a sunset view of the sea stacks before the evening bus back.
May to September is the season for swimming and boat tours, while spring and autumn favour walking and quieter harbours. Summer weekends bring many Catania residents to the coast, so buses and parking can be crowded. Water shoes help on the lava rock, and sun protection is useful because shade is limited.
