About Aci Castello
Aci Castello sits where black lava cliffs drop straight into the Ionian Sea, and the water around the Riviera dei Ciclopi is the real reason to come here — clear enough for snorkelling, calm enough for easy boat trips, and busy with dolphins on many mornings. A short hop from Catania, the coastline pairs basalt sea stacks with Mount Etna looming behind, and you can experience it on the water with trips like the Catania: Boat Tour to Aci Trezza with Dolphin Spotting or the Underwater Archaeological Tour: Acicastello (CT), which takes you over submerged ruins just offshore.

Frequently asked questions
The setting itself: volcanic sea stacks, lava cliffs and clear water along the Riviera dei Ciclopi, with Mount Etna as a backdrop. Boat trips here focus on dolphin spotting, swimming stops and snorkelling over submerged archaeological remains, so you spend the time on the water rather than at a port.
