Walk the largest living medieval town in Greece: a UNESCO-listed warren of Venetian 'kantounia' lanes opening onto the French-built Liston arcade and the Spianada, the biggest square in the Balkans. Duck into the gold-and-silver St. Spyridon church holding the island's patron saint, then climb the Venetian Old Fortress on its sea-promontory for the postcard panorama back over the red roofs. The port is ~2 miles out; the #15 bus or a short taxi drops you in the heart of it.
What to expect
You'll walk into a time-locked Venetian maze: narrow 'kantounia' lanes suddenly open onto the grand French-built Liston arcade and the Spianada—the Balkans' largest square. Step inside the glittering St. Spyridon church to see the relics of the island's patron saint gleaming in gold and silver. Climb the stone ramparts of the Venetian Old Fortress perched on its sea-promontory for postcard views back over the terracotta roofs and harbour. It's intimate, flat, and walkable in 2–3 hours, with no queues or crowds.
The honest answer: skip the tour desk entirely. The ship sells a Corfu Old Town walking tour for $79-99; the Old Town is compact, signposted and a flat 10-minute taxi from the pier, so most first-timers do it free and self-guided. If you want a licensed local guide for the history, Corfu Walking Tours is ~$40-55 — still about half the ship's price and not a bus-herd of 40.
Good to know
The port sits ~2 miles from the Old Town; catch the #15 bus or a 10-minute taxi to drop you in the heart of it. Most visitors skip guides entirely and self-navigate the compact, well-signposted lanes for free; if you want local history, Corfu Walking Tours offers a 2-hour cultural walk for ~EUR 35–50 (about half the ship's tour desk price). Old Fortress entry is EUR 6–10, paid at the gate. Budget 3–4 hours total to enjoy the town and fortress; allow 45 minutes to taxi back and clear the pier before all-aboard.
