Hotels in Aci Castello

Aci Castello is a coastal town on Sicily's eastern shore, roughly 10 km north of Catania. Its defining landmark is a Norman castle built on a basalt lava rock that juts directly into the Ionian Sea — the structure dates to the 11th century and now houses the Museo Civico, which holds local archaeological finds and natural history collections. The surrounding coastline is formed almost entirely from ancient lava flows, giving the water an unusually dark, dramatic appearance against the clear blue sea.

Visitors come primarily for the seafront promenade, the rocky swimming areas, and the proximity to both Catania's airport (Fontanarossa, about 12 km south) and Mount Etna's lower slopes. The town sits within the broader Riviera dei Ciclopi, a stretch of coast named for the basalt sea stacks — the Faraglioni dei Ciclopi — visible just offshore near the neighboring village of Aci Trezza. Day-trippers from Catania arrive frequently in summer, while longer-stay visitors use Aci Castello as a quieter base for exploring the region.

The town's population is approximately 18,000. Local restaurants concentrate along Via Provinciale and near the harbor, serving fresh catch from the Ionian Sea. The castle grounds are open to visitors most days, with modest admission fees.
