Full Day Santorini Tour departing from Heraklion

The volcanic island of Santorini lies north of Crete. And this daytrip by fast catamaran is a great chance to take a close-up look at it. Curved around a colossal, sea-filled caldera that was formed by a massive volcanic eruption 3,500 years ago, it's all black cliffs, whitewashed villages and blue-domed churches. It's picture-postcard Greece. Once you're on dry land, you'll take off on a scenic tour, exploring many of the island's attractions and learning about its history. Explore a caldera-edge town, where whitewashed houses, cobbled streets and tavernas cascade down the cliff-face in steep terraces. You'll then have some free time in both Oia and the island's capital, Fira. Spend an hour or so snapping up treats in the quaint shops and boutiques. Or, visit some of the best lookouts to take photos – the views over the caldera are great. It's made for selfies.
