Taormina's Ancient Greek Theatre, framed by Mount Etna
Climb to the 3rd-century BC Teatro Antico, carved into the hillside so its broken stage columns frame Etna's smoking cone and the Ionian Sea behind them — the single most photographed view in Sicily and the reason cruise lines stop in Messina at all. Reach it fully independently: ~45-60 min train from Messina Centrale (a flat 10-15 min walk from the pier) to Taormina-Giardini, then the local bus or ASM cable car up the cliff. Buy a timed entry ticket on the official park site to skip the queue, and leave time to walk Corso Umberto to the Piazza IX Aprile terrace.
