Aci Castello

Why come

Aci Castello sits ten kilometres north of Catania on the Riviera dei Ciclopi, where the lava-black basalt coast meets the Ionian Sea. The town's anchor is the Castello Normanno (Castello d'Aci), built in 1076 by Roger I of Sicily on a basalt sea-stack thrown up by an underwater Etna eruption around 25,000 BC; the Aragonese expanded it in the 14th century and it now houses the Civic Museum of Aci Castello. Just offshore stand the Isole dei Ciclopi — the seven basalt sea-stacks that Homer identified as the rocks Polyphemus the Cyclops hurled at Odysseus's ship in Book IX of the Odyssey, and which are now a protected marine reserve. The frazione of Aci Trezza (the larger fishing village south of the castle) is where Giovanni Verga set I Malavoglia (The House by the Medlar Tree, 1881), the founding novel of Italian verismo. The coastline between Castello and Trezza is a single black-pebble swimming front, with the dramatic profile of Etna rising behind.

When to visit

Best months · Apr–Oct

Best
Hot or crowded
Quiet
Mostly closed

April through October is the season on the Ionian coast. May and September are the best months: warm Mediterranean sea, lava-rock swimming comfortable, the castle museum at full hours. June brings the patronal feast of San Mauro. July and August are hot and crowded — Aci Trezza in particular fills with Catanian families and the harbour parking goes to chaos by mid-morning. September-October is the value window. November through March is quiet but the castle stays open, the lungomare empty, and Etna's snow-cap most dramatic against the black basalt coast.
